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.
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 constant wasn't very useful as it contained the description of the OS on
the machine where the library was built, not the one on which the application
using it was running. It also wasn't used anywhere in wxWidgets and apparently
wasn't meant to be used outside of it.
Finally, putting the output of `uname -r` into it created problems with
creating reproducible builds as just a change in the kernel version changed
the build results.
Closes#17002.
Use AC_CACHE_CHECK() to avoid recompiling the test program(s) every time
configure runs and also simplify the checks. This required renaming
ac_wxgtkXXX to wx_cv_gtkXXX (cached variables must have "cv" in them).
Also make the checks more logical, by simply setting wx_cv_gtkXXX if
wx_cv_gtkYYY is set with XXX < YYY.
Finally, and the real reason for these changes, add test for __WXGTK220__
which will be used by the upcoming commits to check whether GtkSpinner is
available.
This didn't do (almost) anything, so just remove it, using MFC and wxWidgets
together works just fine without it.

This compiler is not being developed since several years and almost certainly
can't be used to build the current wxWidgets sources anyhow, so remove all
support for it, including a lot of extremely ugly workarounds for its bugs
with template functions.

Most importantly, this allows us to remove all MSLU-related stuff.
Some functions which were previously loaded dynamically can now be just used
directly, too.

Use dladdr() under Unix, if available, to provide the same functionality as we
get from GetModuleHandleEx() under MSW and export it in a new public function.

Under this system vsscanf() is declared as taking a non-const char* as first
argument which prevented our code using it from compiling. Wrap it in
wxCRT_VsscanfA() adding the necessary const_cast<> to fix this.
Closes#15638.
