I agree with Chris, "All things in life are trivial with Perl."
Here's proof:

  find . -name *.[ch] | xargs perl -n -e 'print unless /^\s*$/'| wc -l

This will descend recursively and count non-blank lines in all your
*.c and *.h files.  If you really just want to count up lines from
code in the current directory (without descending into other
directories) try

  perl -n -e 'print unless /^\s*$/' *.[ch] | wc -l

Of course, replace the *.[ch] regex to match source files that are
of interest to you.

Aside:  thanks to Shane Chen, Martin Baehr, Will Yardley, and John
Wenger for replying to my postfix mail problem.  No, I still haven't
solved the problem.  I'm in the middle of composing a long reply
(hope I finish tonight).              -- Al
