Note that this only works for plain C; using diagnostic pragmas (like those
expanded from gnulib's _GL_INLINE_HEADER_BEGIN) to suppress
-Wmissing-prototypes leads to the following warning in C++:

build-gnulib/../config.h:2101:5: warning: option ‘-Wmissing-prototypes’ is
valid for C/ObjC but not for C++ [-Wpragmas]
     _Pragma ("GCC diagnostic ignored \"-Wmissing-prototypes\"") \
     ^~~~~~~
