Perhaps it's not as semi-obvious as you think.  All the world's not SysV.
If you're compiling on a Sun, for instance, you need to re-read the
Release Notes and Porting Guide and pay attention in the section about Sun.  
Specifically, on Sun, you need to add -DNO_REGEX to the list of defines.  
Furthermore, if you're on Sun SPARC, there are some other #defines that you 
will need also.  Sun is just one example; I'm will to bet that there are 
other systems that don't have regex and regcmp.
