dl-runtime.c:56: error: conflicting types for 'fixup'
../sysdeps/i386/dl-machine.h:158: error: previous declaration of 'fixup' was here
when building with gcc-3.4.0

First hunk:
Define ARCH_FIXUP_ATTRIBUTE and use it in the fixup function declarations.
http://sources.redhat.com/cgi-bin/cvsweb.cgi/libc/sysdeps/i386/dl-machine.h.diff?r1=1.124&r2=1.125&cvsroot=glibc
[rediffed against glibc-2.1.3]

Second hunk:
If ARCH_FIXUP_ATTRIBUTE is not defined, provide dummy definition.
Use macro in fixup function definitions.
