This is a GNU/Linux system on dual i686 processors.
>Description:
With -traditional, gcc ignores at least C_INCLUDE_PATH. I
haven't checked the related variables to see if they work.
This has been broken at least since 3.1, but 2.95.3 works.
$ gcc -v

>How-To-Repeat:
$ mkdir foo
$ echo foo > foo/foo.h
$ echo '#include <foo.h>' > bar.h
$ C_INCLUDE_PATH=`pwd`/foo gcc -E bar.h
# 1 "bar.h"
# 1 "<built-in>"
# 1 "<command line>"
# 1 "bar.h"
# 1 "/home/prj/foo/foo.h" 1 3
foo
# 2 "bar.h" 2
$ C_INCLUDE_PATH=`pwd`/foo gcc -E -traditional bar.h
bar.h:1: foo.h: No such file or directory
# 1 "bar.h"
