Hi, 
    My program fileread.c which works ok with my MSC but crashes with
some general protection faults in DJGPP.  Don't know why.

--------------------FileRead.c----------------------
#include <stdio.h>
#include <stdlib.h>
#include <string.h>

int main(int argc, char **argv)
{
  FILE *input;
  char ch;
  int arr;

  for ( arr = 0; arr < argc; arr++ )
  {
    if ( (strcmp(argv[arr],"-help)==0) || (strcmp(argv[arr],"-h")==0) )
    {
      puts("FileRead.EXE v.1\n");
      puts("Usage: C>FileRead -file filename.xxx\n");
      exit(0);
    }

    if ( (strcmp(argv[arr],"-file)==0) || (strcmp(argv[arr],"-f")==0) )
    {
      input = fopen(argv[arr+1], "r");
      if ( input == NULL )
      {
        puts("Cannot open file!\n");
        exit(1);
      }
    }
  }
  
  while (!feof(input))
  {
    ch = getc(input);
    printf("%c", ch);
  }
  fclose(input);
  return 0;
}

This program might have a few bugs but it runs ok in MSC, compiles ok
in DJGPP but crashes when runned.  Any Suggestions?
