====================
All 105 tests passed
====================

I intended to inherit the gcc configuration (and toolchain
as/ld/ranlib/etc since ccc is link-compatible with gcc).  I read through
the docs, looked for "PORTME" in libtool.m4, and can find nothing else
that needs to be modified.  I'm using GNU ld and ccc produces ELF
objects.  Note this compiler worked before with libtool, except libtool
didn't know it could make shared libraries.  Now it does.  :)

Note that g++ and g77 were used and not the Compaq equivalents in 'make
check'.  (But I am just trying to add the C compiler to libtool, not the
others... ;)

It is the companion C compiler to cxx, which libtool already knew about
for linux.  It is the linux port of the C compiler you find in
osf1/Tru64.  You can download it here:
    
ftp://ftp.compaq.com/pub/products/C-CXX/linux/compaq_c_v62/docs/ccc/download_files_.htm
Newer betas require that you register with HPaq though and get a
password.  :(

Compaq/DEC/HP released it mmm...2 or 3 years ago when they realized a
significant number of their customers were using linux on alpha.  It
produces significantly better code than gcc 3.2 on alpha.
