Nothing but auxvec.h Well, sys/procfs.h on several arches includes : find -type f -a -name \*.h | xargs grep '<\(asm\|linux\).*elf' ./sysdeps/unix/sysv/linux/alpha/sys/procfs.h:#include ./sysdeps/unix/sysv/linux/sh/sys/procfs.h:#include ./sysdeps/unix/sysv/linux/sys/procfs.h:#include while most other arches don't need it: for i in `find . -name procfs.h`; do grep -q '<\(asm\|linux\).*elf' $i || echo $i; done ./sysdeps/unix/sysv/linux/s390/sys/procfs.h ./sysdeps/unix/sysv/linux/powerpc/sys/procfs.h ./sysdeps/unix/sysv/linux/sparc/sys/procfs.h ./sysdeps/unix/sysv/linux/i386/sys/procfs.h ./sysdeps/unix/sysv/linux/ia64/sys/procfs.h ./sysdeps/unix/sysv/linux/x86_64/sys/procfs.h Guess it shouldn't be hard to convert even alpha and sh (not sure then if there are any arches that actually use the linux/sys/procfs.h header).
