I'm not sure what you mean by `system regex', but emacs does certainly depend on non-standard features of the GNU regex code, namely the interface which allows searching across the buffer-gap. So emacs can't use any `system regex' that doesn't define this interface. AFAIK, the new regular-expression implementation in glibc actually _has_ that interface, but it works in a completely stupid (and essentially useless) way, so emacs shouldn't use it -- but that situation might be hard to detect using standard autoconf methods. -Miles -- o The existentialist, not having a pillow, goes everywhere with the book by Sullivan, _I am going to spit on your graves_.
