RE: libiberty testsuite builds with wrong compiler

[Jack Howarth <howarth at bromo dot med dot uc dot edu>]

  The same issue in the libiberty testsuite run can be seen with
the Apple regress server log at http://gcc.gnu.org/regtest/HEAD/native-lastbuild.txt.gzip.
If you search for test-demangle, you will find...

etc. All of which are using the system c compiler instead of that from gcc trunk.
