[Msys2-users] missing realpath() and canonicalize_file_name()

[folkert <fo...@va...>]

Hi,

It looks like the realpath and canonicalize_file_name posix calls are
missing from msys2.

#define _GNU_SOURCE
#include <limits.h>
#include <stdlib.h>

int main(int argc, char *argv[])
{
        realpath("test", NULL);

        canonicalize_file_name("test");

        return 0;
}


On linux:

11:15:48 folkert@belle:~↥ 40s $ gcc can.c
11:15:51 folkert@belle:~↥ $ ./a.out
11:15:53 folkert@belle:~↥ $


On msys2:
