Upstream-Status: Inappropriate [debian patch]

This patch address a namespace collision with libc.

Although there is no "#include <regex.h>" in the source file, at
runtime, it's unintentionally linked to the libc version, the regcomp of
libc is called instead the pcre one using pcre's data structure...
that looks like a disaster.

Can patch is from Debian (and Ubuntu 11.04alpha has it also).
