libc5 enviroment under glibc6?

[Oliver Dawid <od at fet dot uni-hannover dot de>]

hi there,

i am trying to compile some stuff for the libc5 but i dont succeed. the
system libc is glibc-2.2.2.

gcc-2.95.3
libc-5.4.38 (rpm from redhat)
RedHat 7.1

i deinstalled the gcc-2.96 and binutils and installed the gcc-2.95.3
an binutils from the tarballs from ftp.gnu.org

here is a little test:

[od@bart ttt]$ cat test.c
#include <stdio.h>
 
int main ()
{
  printf("Hello world!\n");
  return 0;
}
