The 2.11c libraries don't do setpgrp right. setpgrp is BSD's name for
setpid (actually BSD had it first and POSIX took it and changed the name).
So, the prototype in <unistd.h> should give setpgrp 2 arguments (and
should be protected by an #ifdef __USE_BSD as well) and the implementation
has to be fixed in libc-2.11c/unistd/setpgid.c as well. The easiest way
to do this is to rip out the broken def of setpgrp in setpgid.c and use:
#include <gnu-stabs.h>
symbol_alias(setpid, setpgrp)
On a completely different note, execp still doesn't handle null path
components correctly (should treat PATH=:/bin same as PATH=.:/bin).
I recommend using GNU's execp or BSD's execp, both of which seem to
work fine.
