The regex library shipped with geany is from 2002 (or earlier, I don't
know) so it's pretty old. It would be best to upgrade to the latest
one from glibc (or the one that ships with the latest ctags which
appears to be from 2009).

By the way does geany have to provide its own copy of the regex
library? Isn't it already required by glib or gtk? It's also probably
available on every unix system, I'm just not sure in what environment
geany is compiled under windows.
