 completed in 0 seconds

This doesn't happen when I use the system's gcc compiler for initial bootstrap.
However, it doesn't support Ada, so I use my own gcc build for bootstrap.

export CC=gcc
export
PATH=/opt/gnu/gcc/gcc-4.3.2/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/
bin:/usr/X11/bin

When GCC_EXEC_PREFIX is not set in the environment, gcc finds the installed
cc1.  However, when GCC_EXEC_PREFIX is set in the environment to the null
string, gcc doesn't find cc1.

We have this code in struct-layout-1.exp:

# Temporarily unset GCC_EXEC_PREFIX from environment, as that might
# confuse the $HOSTCC.
set orig_gcc_exec_prefix_saved 0
if [info exists env(GCC_EXEC_PREFIX)] {
     set orig_gcc_exec_prefix "$env(GCC_EXEC_PREFIX)"
     set orig_gcc_exec_prefix_saved 1
     unsetenv GCC_EXEC_PREFIX
}

For some reason, the dejagnu "unsetenv" command doesn't actually unset
GCC_EXEC_PREFIX on darwin9.

> This is really PR 36443.

Aside from darwin specific issues with the environment, the problem looks
the same.  Did anybody try Mark's suggestion (i.e., setting HOSTCC to
"unset GCC_EXEC_PREFIX && gcc")?

Other C cpmpilers may be used for bootstrap.

If this is still a problem, please try the patch at

  http://gcc.gnu.org/ml/gcc-patches/2009-01/msg01496.html

I'd rather not make changes like that so late in the release cycle but I'll do
it if it's needed and not just cosmetic.

Yes, this is still a problem on darwin.  The patch fixes the PR.

I would say the issue is more than cosmetic, but testsuite issues aren't
crucial unless the test results are misleading.
