Hi,
It seems that the flex has a bug. ( and it still hasn't been corrected apparently as the version I run is 2.5.35)
The following is the solution suggested in the bison info. /* Work around an incompatibility in flex (at least versions 2.5.31 through 2.5.33): it generates code that does not conform to C89. See Debian bug 333231 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=333231. */ # undef yywrap # define yywrap() 1
But then why does this problem arise only when I use autotools. I never faced this problem while I was using a handmade Makefile?
