That warning seems very impractical in code dealing with GetProcAddress. In
Wine, we usually just cast it to (void *), but I recall that it was
problematic for mingw-w64-crt for some reason too. Maybe we could just
disable that warning in the configure script?
It's required by POSIX, but casting between a function pointer and an object
pointer can produce a warning with `-pedantic`.
It looks like GCC warns in C and Clang warns in C++. /facepalm
Hmm, can you give a godbolt example or similar, for where the compilers
diverge about warnings here?
With Clang, I don't seem to be able to get any warnings for either casts
via (void(*)(void)) or (void*), with either C or C++, with -Wall -Wextra
-pedantic.
