* .purify: New file: suppress some known-OK Purify messages.
* read.c (read_makefile): Remember to free the commands buffer if
we can't find a makefile.
* job.c (start_job_command): Broken #ifdef test: look for F_SETFD,
not FD_SETFD. Close-on-exec isn't getting set on the bad_stdin
file descriptor and it's leaking :-/.

* read.c (read_makefile): Fix some potential memory stomps parsing
