Regex, clitar.c and Autoconf

[Richard Sharpe]

Hi,

I am modifying clitar.c to use the following approach with respect to
regex.h and friends:

If CLITAR_USE_REGEX is defined, then the code will use regcomp and regexec
for doing regular expression matches, otherwise mask_match will be used.

CLITAR_USE_REGEX will be off by default.

This brings up a issue with respect to autoconf.

We need a way of specifying the names of defines that autoconf will set
based on what it finds in the OS. Perhaps the person/people doing the
autoconf work should be the keeper of these names and should specify the
naming convention.

Perhaps the define above is wrong, and should simply be HAS_REGEX.



Regards
