   I just got the following error message when trying to compile:

   cd /home/ejh/nmc_link/
   gcc -o split84 split84.c
   /usr/bin/ld:
   Undefined:
   pow
   collect: ld returned 1 exit status

   But I did include math.h, and looking in /usr/include/math.h I see a
   pow and a powf function. (I tried both). What am I doing wrong here?

Of course, as soon as I posted I realized that I hadn't included -lm
in the compile command. I canceled the article, but in case it did get
out first, I just wanted to appologize for asking such a dumb
question. On the other hand, maybe it will make some people happy to
have such an easy question that will make them feel smart because they
know the answer!  ;-)
