#include <sys/stat.h>
#include <errno.h>
#include <stdio.h>
int main () {
   if (mkdir("C:",0755)<0) printf("C:  -> errno: %d\n",errno);
   if (mkdir("C:\\",0755)<0) printf("C:\\ -> errno: %d\n",errno);
   if (mkdir("C:/",0755)<0) printf("C:/ -> errno: %d\n",errno);
   if (mkdir(".",0755)<0) printf(". -> errno: %d\n",errno);
   if (mkdir("hexen2",0755)<0) printf("hexen2  -> errno: %d\n",errno);
   if (mkdir("hexen2\\",0755)<0) printf("hexen2\\ -> errno: %d\n",errno);
   return 0;
}

Running the exe from C:\ prints the following:

Under dosbox:

C:  -> errno: 10
C:\ -> errno: 22
C:/ -> errno: 10
. -> errno: 10
hexen2  -> errno: 10
hexen2\ -> errno: 22


Under dosemu:

C:  -> errno: 10
C:\ -> errno: 10
C:/ -> errno: 10
. -> errno: 10
hexen2  -> errno: 10
hexen2\ -> errno: 10

(Can't run under pure real dos at the moment.)

That would be you, but not me,

No, that won't be my suggestion. I can't see how a 500% irrelevant
flag var can go into crt1.c.  Feel free to do so yourself, though.

Regards.
