[Python-Dev] ANSIfication breaks socketmodule compile...

[Mark Favas]

The recent bout of ANSIfication seems to have raised a couple of issues
with socketmodule:

1) It now won't compile on Tru64, because the declaration of
"gethostname" on line 114 conflicts with that in the system unistd.h
header file. 114 declares the second parameter as size_t, unistd.h
declares it as int (unless the macro _XOPEN_SOURCE_EXTENDED is defined,
but that's another can of worms...). The simple fix here is to add
another !(defined(__osf__) to the preceding #if line.

2) There'll be an issue on those platforms where the second parameter
_is_ declared as type size_t, because the gethostname function is called
at line 1402 with the second parameter cast to an int, rather than a
size_t...
