Could you please explain what "unable to compile" means? What platform are you on?

I have Fedora 7 with gcc-4.1.2-12 and was trying to compile LFS.
Something went wrong and i opened compat/memcmp.c to see what.
Can you just look at the code i think it is trivial.

Thanks Mladen

This is a duplicate of bug #1631017, which is reported as fixed in both HEAD and 8.4. The files on HEAD and core-8-4-branch differ: is there a reason for that?

Assigning to dkf as he reported this fixed.

From comments in #1631017:

| The real bug is that compat/memcmp.c is being used in the first place -
| if the build system is trying to use this file at all, it indicates that
| the configure script has failed to detect a working C compiler.

Other reports indicate that this happens when trying to cross-compile.
One proposed solution is to use AC_TRY_LINK instead of AC_TRY_RUN.
(sorry, reference not handy, I just vaguely remember reading this somewhere).

Fixed the obvious fault in compat/memcmp.c; I won't try to think about the bugs relating to why that file exists or is used.
