Apparently this still doesn't display any scrollbars in the window itself, so
from our point of view it is equivalent to GTK_POLICY_NEVER.

Don't mix statements and declarations, this is not allowed in C89.
Fixes compilation with MSVC <= 10 after 74da7cba07

This is a modified version of the patch from Mozilla (see
https://hg.mozilla.org/releases/mozilla-esr31/rev/2f3e78643f5c) which was also
applied to Chromium. This version prefers to use the buffer of the correct
size instead of just returning an out-of-memory error if the size needed is
relatively (but not extraordinarily so, e.g. just slightly more than 64KB in
32 bit builds) big.
Unlike the similar (identical?) SetUserScale(), this function didn't call
RealizeScaleAndOrigin(), add it now for consistency.

See #17053.
Don't apply Watcom workaround for empty vararg log functions to MinGW, it
doesn't seem to need it and using it actually breaks compilation of the code
in wxWidgets itself when wxLogSysError() is used with wxString argument.
Closes#17048.
Implement Freeze() by blocking the GtkWindow "expose-event"/"draw" signal
instead. Since the introduction of client-side windows in GTK+ 2.18,
gdk_window_freeze_updates() is unuseable because the impl_window (and thus the
update_freeze_count) for a given GdkWindow can change unpredictably. See #16795
This should prevent an assert failure which happens if we call Accept() on an
invalid server below and also confirm if the server creation really failed or
not.
Its value (0x80000000) is outside of the int type range on 32 bit platforms,
but we still want to allow using it as an initializer of int and/or long
variables for consistency with the other types, so cast it to int explicitly
to suppress -Wnarrowing warnings from recent g++ which were given when doing
this before.
Recent g++ versions give -Wnarrowing warning when a value outside of the type
range is used to initialize a variable of this type in { }. Avoid it in the
long long tests using explicit casts as we already cast between long long and
unsigned long long values here anyhow.
g++ 4.8.2, shipped with Ubuntu 14.04, generates incorrect code for checking
the loop termination condition, resulting in never ending loops in
HashMapTest().
Disable the optimizations for this function for 4.8.[012] as the bug seems to
be fixed in 4.8.4 and several similar (but not really identical) bug reports
in gcc bugzilla have been fixed in 4.8.3.
This should allow the unit tests on Linux buildbots, using 4.8.2, to run to
completion again.
Valgrind complains about reading beyond the end of buffer when using glibc
std::string for wxString implementation under amd64 Linux. Don't suppose that
the buffer has one extra null word at its end to avoid this.
Use wxUIntToPtr() to suppress the warning, we know that the cast here is safe
because Windows uses only pointers fitting in the UINT range for the menu (and
other) handles.
Set ms_isThemeEngineAvailable to -1, meaning that we need to reinitialize
themes, instead of false, meaning that themes are not available.
This fixes problems when the library is initialized, shut down and then
initialized again.
Closes#17023.
Don't ignore errors (this resulted in warnings in optimized builds because
variable "hr" containing the error code to was assigned but never used) and
don't leak memory in the (admittedly unlikely) case an error really occurs.
Also don't duplicate the code for creating a one element SAFEARRAY<VARIANT>,
extract it into a helper function.
Don't cast NMHDR::code field to int, this cast was added in the previous
millennium, probably to work around the wrong definition of NM_DBLCLK in some
ancient MinGW headers, but nowadays all MinGW distributions (tested with
MinGW 4.8.1, MinGW-64 4.9.1 and TDM-GCC 4.9.2) define it correctly and so
using this cast results in a warning -- just remove it to get rid of it.
Including standard math.h header with both -O2 and -std=c++NN options results
in compilation error due to a bug in the header, see MinGW bug report at
https://sourceforge.net/p/mingw/bugs/2250/
Work around this to allow the library to compile in release build with
-std=c++11. This is ugly but better than failing to compile at all.
These options enable "strict ANSI" mode in MinGW which omits declarations of
POSIX functions from the standard headers. To allow the library and, possibly
even more importantly, the user code including our headers, to compile with
these options, declare the functions that we need ourselves.
This might appear to go against the spirit of "strict ANSI" mode, but the only
alternative would be to not use such functions at all and silently cripple the
library when -std=c++NN is used, compared to -std=g++NN case, and this doesn't
seem appealing neither.
Closes#16984.
g++ 4.9.2 added support of __has_include() but, unlike clang, refuses to
compile the <type_traits> header that is detected as existing now in C++98
mode, so the build was broken with it when not using configure (i.e. under
MSW).
Fix this by, first, testing for C++11 compilers separately (which seems like a
good idea anyhow as it will allow using these headers with other compilers)
and, second, not trusting g++ __has_include() for C++11 headers in C++98 mode.
This doesn't make much sense for an interface declaration anyhow and produces
a warning from g++ about assigning string literal to (non-const) BSTR pointer.

This class doesn't really need a virtual dtor as it's never used
polymorphically, but add it to avoid g++ warnings about it.

Interpret internal compiler version value 1900 as VC14. Notice that this
required adjusting the computation of the internal version from the
user-visible one because VC13 was skipped (hopefully no black cats crossed
paths with the manager responsible for this decision).

This MSVC version does add snprintf(), finally, and doesn't allow
pre-#defining it before including its stdio.h, so don't do this.

Starting with Vista, SetThreadLocale() does basically nothing and does
not affect UI language. We need to call SetThreadUILanguage() as well
from wxLocale::Init() to have the locale reflected in e.g. standard
dialogs.
Don't stop converting subsequent chunks just because the length of one of them
was 0: this can happen if the first character of a string is a NUL or if there
are two (or more) NULs in it later.
Simply remove the check for this and continue as usual even in this case.
Also add a unit test verifying that we do translate NULs in input into NULs in
output.
Closes#16620.

Visibility support for Clang was disabled in 7198c33 because of linking
errors when building shared libraries, related to non-inline methods in
exported template classes.
The last Clang version to have these problems is version "4.1
(tags/Apple/clang-421.11.66)" as part of Xcode 4.5.2, and the next
release fixes them (version "4.2 (clang-425.0.24)", Xcode 4.6). Check
for the Clang version and only disable visibility support when compiling
with Apple Clang < 4.2.
Note that Apple Clang 4.2 is based on official Clang 3.2 so also check
for that version in case of non-Apple builds. The only official Clang
that has been tested successfully is 3.4 which worked fine with
visibility. Other versions that were tried (3.1 and 3.2) segfault while
compiling wx.

The flicker was only visible under Windows XP or when using a class theme
and was due to mis-positioning the status bar initially in PositionStatusBar().
Fix this by adjusting its position by the toolbar offset before calling its
SetSize().
Closes#16705.

The expected result in this case is ".", but the filename became empty instead
when wxPATH_NATIVE was used.
Fix this by examining GetFormat(format), which takes care of mapping
wxPATH_NATIVE to its real value, instead of wxPATH_NATIVE itself.
Also add a unit test verifying that this works as expected.
Closes#17010.
