GStreamer media backend: Fix building on Visual Studio
Hi,
From the commit message:
Visual Studio (and possibly other non-GCC compilers) do not like uses of #-preprocessor directives in function-like macro usage (warning C5101: use of preprocessor directive in function-like macro argument list is undefined behavior
is also shown), so fix the build by defining another macro accordingly.
This will apply in the main and gtk-4-14
branches.
With blessings, thank you!
