I do not see this error in my build of microblaze-elf.

I notice that there are flags in your compile that do not appear in mine:
-pedantic -Wno-long-long -Wno-variadic-macros -Wno-overlength-strings -Werror

I don't see any warnings in my build, either.

My build is using gcc-4.1.2 (on CentOS 5.9) as a build compiler.  My
guess is that this is the cause of the differences.

I'll upgrade to building with a more recent version of gcc and investigate
this failure, but I won't be able to look at this for about two weeks.
