+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).
