A quick note about this non problem. re2c works pretty well on windows and they provide a .exe as far as I remember (much easier than flex which requires cygwin or gnuwin32, even if both work :). Besides the portability of re2c, we already use it in some extensions (if I remember correctly) and nobody complained. Cheers, -- Pierre http://blog.thepimp.net | http://www.libgd.org
