Stephan Bergmann 8279d89d6e external/libassuan: Fix fallout of defining __STDC__ on Windows 
...since 1bb0e17712 "Fix autoconf>=2.70
gcc-wrapper breakage", which had the side effect of preventing various
deprecated function declarations in system headers (e.g., isascii in addition to
__isascii).  This went unnoticed so far due to the traditionally lax handling of
missing function declarations in C, and only now started to cause

> conversion.c(94,9): error: call to undeclared function 'isascii'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]
>           if ((isascii (*istr) && isprint (*istr)) || (*istr >= 0x80))
>                ^

etc. with clang-cl 15 trunk after
<7d644e1215>
"[C11/C2x] Change the behavior of the implicit function declaration warning".

Where undeclared functions have been used in Windows-only code, they have been
replaced with their __STDC__-declared counterparts, and for occurrences in
shared code Windows-only macro definitions have been introduced (as would have
done in the system headers too, if __STDC__ was not defined) to not clutter the
shared code with #ifdefs.

Also, for getpid (resp. _getpid), the #include <process.h> was apparently
missing from the upstream code, even without our __STDC__ hack in
external/libassuan/ExternalProject_libassuan.mk (but never caused errors until
now, either).
