Details:

When compiling GRUB 2.00~beta6 I run into this compile error:

==========================================================

As a workaround, I used ./configure --disable-werror but I suppose you want to
fix all warnings if -Werror is upstream default.  My version of GCC is 4.5.3.

The issue may be related to issue 26510 [1] but as that is two years old and
makred fixed, I assumed it would be something new.

Best,



Sebastian
