------- Comment #5 from anhvofrcaus at gmail dot com 2009-11-02 23:56 ------- The complain is the direct result of not have flex.exe on my system. After installing flex, this complain goes away. However, the original problem shows up again. The configuration for the build is
$ ../gcc-4.5-20091015/configure --enable-languages=ada,c,c++,fortran --with-gmp =/c/tools/gmp-4.3.0/ --with-mpfr=/c/tools/mpfr-2.4.1/ -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41709
