Hi
Below patch fixes build failure on FreeBSD. FreeBSD ships with very
old version of flex (in /usr/bin), which is now obsolete. This patch
adds a configure time check for flex version to be >= 2.5.35. FreeBSD
users can build GRUB by specifying LEX=/usr/local/bin/flex to
configure command line (similar to CFLAGS, etc) for building with more
recent flex.
