I've just invoked one alpha-dec-osf5.1 testcase that failed with -v:

cc1: Unrecognized option `-fencoding=UTF-8'
collect2: gcc returned 1 exit status

So -fencoding is passed (via COLLECT_GCC_OPTIONS) to the gcc invoked by
collect2.  I don't understand the code in gcc.c enough to suggest a fix,
though.

Thanks, installed.
