I have encountered the same problem.  The following code works fine when
compiled as a DJGPP DOS program, but crashes at the first feof(infile) call
with "Exception at 0x00000000; Application got SIGSEGV" when compiled
with -Zwin32:

#include <stdio.h>
#include <stdlib.h>
main (int argc, char *argv[])
 {
 int c;
 FILE *infile;
  infile=fopen(argv[argc-1],"r"); {
    printf("Unable to open input file %s.\n\n",argv[argc-1]);
    exit;
   }
  while (!feof(infile)) {
    if ((c=getc(infile))==EOF)  {
      printf("\nEOF.\n"); fflush(stdout);
      break;
     }
    else putchar(c); fflush(stdout);
   }
 }


Does anyone know why this happens?  Is my RSXNTDJ installation not
configured right?

Brad
