simple C example calling getcwd

in wine 5.11, getcwd always returns Z:\ whatever the current dir wine is run
from
this is from archlinux x86_64

try compile this main.c with mingw and run it:

#include <unistd.h>
#include <stdio.h>
#include <limits.h>

int main() {
   char cwd[PATH_MAX];
   if (getcwd(cwd, sizeof(cwd)) != NULL) {
       printf("Current working dir: %s\n", cwd);
   } else {
       perror("getcwd() error");
       return 1;
   }
   return 0;
}

$ cd /tmp
$ x86_64-w64-mingw32-gcc main.c
$ wine a.exe
Current working dir: Z:\

with wine 5.10 we get:
Current working dir: Z:\tmp
