yann@1: dl-runtime.c:56: error: conflicting types for 'fixup'
yann@1: ../sysdeps/i386/dl-machine.h:158: error: previous declaration of 'fixup' was here
yann@1: when building with gcc-3.4.0
yann@1: 
yann@1: First hunk:
yann@1: Define ARCH_FIXUP_ATTRIBUTE and use it in the fixup function declarations.
yann@1: http://sources.redhat.com/cgi-bin/cvsweb.cgi/libc/sysdeps/i386/dl-machine.h.diff?r1=1.124&r2=1.125&cvsroot=glibc
yann@1: [rediffed against glibc-2.1.3]
yann@1: 
yann@1: Second hunk:
yann@1: If ARCH_FIXUP_ATTRIBUTE is not defined, provide dummy definition.
yann@1: Use macro in fixup function definitions.
