The latest flex makes the GRUB-2.00 build fail. I can work around the
issues with --disable-werror, but grub-core/script/yylex.l causes two
warnings that do not work with -Werror.
./grub-core/script/yylex.l: At top level:
grub_script.yy.c:2351:13: error: 'yy_fatal_error' defined but not used
This can be fixed by removing #define YY_FATAL_ERROR(msg) in yylex.l.
grub_script.yy.c: In function 'yy_scan_bytes':
grub_script.yy.c:2296:17: error: comparison between signed and unsigned
integer expressions [-Werror=sign-compare]
This one is a little more difficult because it is generated by flex. I
don't know how to fix this except with a sed after grub_script.yy.c is
generated by flex.
The gcc version -s 4.7.1.
