Clarity and portability. I'm not above writing a set of library routines
to make my life easier (the Software Tools distribution is a good example
of such a set) but except for "extreme" circumstances, it's not clear that it's
worth it to the N'th guy down the line who has to maintain the code.

At the University of Oklahoma, our PDP-11 software came from the Purdue/ECN:
this gave the person setting up this machine a fine base to start with. The
one thing that constantly bit us was a person there who wrote all his programs
(system-wide programs, like the editor!) to use HIS OWN VERSION of the Standard
I/O library. This guy #include'd it from his HOME directory! (No, John, it
wasn't you.)

Try maintaining that.
