Regarding issue itself - it appears bug in flex, introduced in 2.6.3. The conflicting defines are under %if-not-reentrant, and grub has "%option reentrant" in its yylex.l. Other projects are affected as well.

Thank you, but please, either file separate bugs for separate issues, or use grub-devel for such reports (even better, send patch to grub-devel).

Completely tangentially, there's a typo in configure.ac, line 280 (stray quotation mark).

Building GRUB with flex 2.6.3 generates an error message about macros yyalloc, yyfree and yyrealloc being redefined.

Adding #undefs in yylex.l fixes it.
