I expect that this is a problem with your shell, not with the C compiler.
Can you please verify this by sending us the first line of "zgrep"?
My guess is that it reads "#!/bin/ksh"; that would probably explain things.
I'll look into writing a fix. The problem is that the script assumes
that if it makes file descriptor 6 open on a file, then that file descriptor
is inherited by child processes: but POSIX does not guarantee this for the
shell, so the script is not portable to ksh.
