Dickey > http://invisible-island.net > ftp://invisible-island.net reflex seems like a better solution for us than upgrade to flex (from sourceforge) imho, flex depends on m4 and on some gnu m4 extensions, normal= ly our version of m4 is now compatible with gnu m4 (I added some missing bits recently) but still I don't think having flex using m4 is a good idea, and reflex looks cleaner in that area. reflex is just missing imho one feature from flex (sourceforge version) tha= t is ability to generate reentrant code. I already imported byacc from invisible island, I was supposed to add some "fixes" to byacc (bde has spotted) and provide them to Thomas, sorry I have been slacking in that area recently. Once that is done, I have on my todo list importing reflex to replace our f= lex. I did feel any hurry in that area, as I don't think we are missing too much features, is there one you are particulary interested on? I was waiting for reflex to support reentrant code generation before importing it. regards, Bapt --uk6W7isEeLAaRh3S Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.19 (FreeBSD) iEYEARECAAYFAlAYRzcACgkQ8kTtMUmk6EymOACeICfDi+PKUWFZgt07bKtaLeEj L18AoKTi/faAXjILCyHtBUp1YdFoO5/q =bOlp -----END PGP SIGNATURE----- --uk6W7isEeLAaRh3S--
