This is useless, all still supported compilers except ancient MSVS
versions (for which configure is not used anyhow) support variadic
macros, so don't waste time testing for them.
Note that the checks for HAVE_VARIADIC_MACROS in the sources are still
left because it is still possible to explicitly disable variadic macros
support using --disable-vararg_macros for strict C++98 compatibility.
All still supported versions of MinGW/Cygwin provide w32api.h file, so
there is no need to test for it.
This allows to simplify the code, but also remove the definition of
HAVE_W32API_H from bake- and makefiles and this, in turn, allows to get
rid of extra flags in MinGW format entirely, as we don't support gcc
2.95 for which they were originally needed neither.
Remove separate checks for dlerror() which don't seem to be needed under
any platform any longer.
No real changes, just slim down configure/CMake a tiny bit.
This function is not used any more since e289eb07e1 (Get rid of
non-POSIX code for loading dynlibs on *nix, 2020-05-13), so don't check
for it and don't defined the corresponding HAVE_SHL_LOAD symbol.
It defaults to 1, but can be set to 0 to force using the generic version
of the control even under GTK or Mac, where the native version is used
by default.
This can, unfortunately, be useful to work around various but multiple
native control limitations.
This is not really an option as building requires it to be 1, so don't
make it one in setup.h/configure/cmake and just hardcode it as 1 for
compatibility.
Closes#18558.
This is always 0 for any still supported compiler, so remove the option
and configure checks for it.
Still define it as 0 for compatibility, just in case it's used outside
of the library.
Including <winsock.h> and <winsock2.h> is incompatible and if the
application wants to use the latter, it may be convenient to define
wxUSE_WINSOCK2 when building wxWidgets instead of having to work around
winsock.h implicit inclusion from include/wx/msw/wrapwin.h.

Prepare for using liblzma in wxWidgets code by adding the necessary
option and updating the configure check for it (which had been already
present due to libtiff possible dependency on liblzma).
No real changes yet.
Commit bc13119494 removed the inclusion of
xlocale.h because it is not (and never was) needed under Linux with
glibc, but it is still needed under macOS, so this (silently) disabled
wxXLocale support under Mac when using configure and broke the build
when using cmake.
Fix both problems by using xlocale.h only if it's available, both in
configure and in cmake.
Add CMake-based build system.
Merge the original branch without any changes except for resolving the
conflict due to moving the contents of .travis.yml to a separate file by
propagating the changes done in this file since then to the new script
and rerunning ./build/update-setup-h and ./build/cmake/update_files.py
to update the file lists changed in the meanwhile.
Closes https://github.com/wxWidgets/wxWidgets/pull/330
Add CMake build system for libraries, tests and samples
update_files.py converts build/files into CMake format.
build/update-setup-h has been modified to update build/cmake/setup.h.in.
