#include<stdio.h>
int main(void)
{
  return 0;
}

That is exactly the code that produced the error
message I posted.

IIRC I downloaded DOSLFN from that link.  I will try an older
version ASAP.
OFYI, I have djgpp 2.03 installed on the same partition with the same
MSDOS 6.22 so I can choose if I want to compile with 2.04 or 2.03.
gcc 4.6.1 and djgpp-2.03 work flawlessly.
