define WINVER as 0x0400 for VC++ 6 because its headers give a warning if WINVER >= 0x0500 is used and are generally broken for higher WINVER values

/*
see MSDN for the description of possible WINVER values, this one is the
highest one defined right now (Windows Server 2003) and we use it unless
it was explicitly overridden by the user to disable recent features
support as we check for all of the features we use which could be not
available on earlier Windows systems during run-time anyhow, so there is
almost no disadvantage in using it.
The library user may override the default setting of WINVER by defining
it in his own makefile or project file -- if it is defined, we don't
touch it at all.
It makes sense to define WINVER as:
- either some lowish value (e.g. 0x0302) to not even compile in the
features not available in Windows version lower than some given
one
- or to a higher value than the one used by default for the given
compiler if you updated its headers to newer version of Platform
SDK, e.g. VC6 ships with 0x0400 headers by default but may also
work with 0x0500 headers and beyond

VC6 defines some stuff in its default headers which is normally
only present if WINVER >= 0x0500 (FLASHW_XXX constants) which
means that our usual tests not involving WINVER sometimes fail
with it, hence explicitly define a lower WINVER value for it.
