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?
