index == strchr
rindex == strrchr

Well, I would have mailed this if it hadn't triggered a question that's
been floating in the back of my head for the last five years.

Is there something like a porting guide for C-programs under Unix?
This guide would present the differences between all the main variants
of Unix.  Specifically differences in library functions and ioctl commands
are interesting.  I know the knowledge is out there, has anyone written
it down?
