I don't believe that anything in the core OS uses cpp, but I know at least one port that cares about __ELF__ does (archivers/zip). >How-To-Repeat: On a system where the default object format is elf: touch foo.c cc -E -dM foo.c cpp -dM foo.c Note the __ELF__ is listed in the former but not the latter output. >Fix: Since /usr/bin/cpp is a wrapper script, fixing it seems less intrusive than grafting objformat's functionality into /usr/libexec/cpp. This patch does that: *** usr.bin/cpp/cpp.sh.orig Sat Feb 22 14:54:47 1997 --- usr.bin/cpp/cpp.sh Mon Sep 7 02:32:17 1998 *************** *** 50,55 **** --- 50,60 ---- INCS="-nostdinc" FOUNDFILES=no + if [ `objformat` = "elf" ] + then + ALST="$ALST -D__ELF__" + fi + for A do case $A in >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
