That's really a pity. If we really need regex'es, the most simple code could be fetched from NetBSD. It has the advantage to be single-byte only. Paths in the distro shouldn't use multi-byte strings anyway. OTOH, it might be sufficent for quite some time, if the autodep strings are only evaluated as simple filename suffixes: autodep: .oct .so .dll autodep: .info .info.gz Wouldn't that be sufficent and very easy to implement?
