Thanks Paolo!

The documentation I found for gnu-regex 0.12 is:
http://www.delorie.com/gnu/docs/regex/regex_toc.html

The whole library seem to be quite outdated (early 90'), I could
not even find a home page for it :-(

I tried the [:space:] character class before I posted this question
and it did not work. So I either made a mistake or not even gnu-regex
is not fully supported. None of the existing .lang files are using
character classes.

Now, character classes are not a big deal, but if the full gnu-regex
is not supported then what exactly is?


pcre is much nicer, how far is an implementation using it?
