Right, whereas in other parts of the GNU APIs there are rather more liberal additions (just grep the man pages for _GNU_SOURCE). What's the reason not to make more GNU extensions to the POSIX APIs (including new functions that work with the existing POSIX functions, not just changes to the semantics of existing calls), rather than updating an API that is much less widely used than either POSIX or PCRE? Keeping two regex APIs alive indefinitely in GNU seems rather perverse... > Adding syntax bits to PCRE would be nice indeed, but then PCRE > does not guarantee POSIX leftmost-longest matching like GNU > regex does. Sure, pretty much every different regex library lacks features that others have. -- http://rrt.sc3d.org
