Hi,

I get the following compiler error when building GCC 4.8
(gcc-4.8-20120812) on an x86_64 system running Scientific Linux 6.2.

I think this means you need to install Flex 2.5.4 or later.

http://gcc.gnu.org/install/prerequisites.html documents it as
"Necessary to build GCC during development because the generated
output files are not included in the SVN repository. They are included
in releases. "
