mingw does not define getpagesize as far as I can tell with:
$ grep -nr getpagesize /usr/i686-w64-mingw32/include/
but gcc seems to detect it (9.x and 10.x):
checking for getpagesize

I found this in stddef.h:
#ifndef __WCHAR_TYPE__
/* wchar_t is unsigned short for compatibility with MS runtime */
#define __WCHAR_TYPE__ unsigned short
#endif

Add yes, your C testcase leads to the same results.

--- Comment #2 from xantares09 at hotmail dot com ---
Thanks for the quick reply.
On mingw __WCHAR_TYPE__ expands to short unsigned int:
$ x86_64-w64-mingw32-gcc -E main.c
...
# 3 "main.cxx"
int string_hash(const short unsigned

I can confirm the patch from gcc-5 branch applied on top of 5.2.0 fixes the
mingw problem.
Thanks a lot.

Note that you'll need mingw-w64 4.0.4, not 4.0.2 to reproduce, I used gcc
5.2.0.
