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.
