Log message:

	Generate a configure error if we can't find lex/flex or yacc/bison, as they're essential for compiling.  Also
check to make sure we can find a LEXLIB; I've noticed that on Debian SPARC, at least, the installed lib won't work if
you use gcc3 - now generate a failure notice with a note about checking which compiler version you're using.  Much
better that getting half way through the compile to find that something we need is missing.
