iliaa Mon Dec 2 02:03:01 2002 EDT Modified files: /php4 configure.in Log: Fixed flex version check. Some lex scanners like Sun's SGU do not appear to support -V flag, so by passing them data on stdin we prevent them from sitting idle waiting for stdin data. I've also added some common version retrieval flags, that may be supported by various lex scanners.
