   Writing a compiler is a daunting project (ask the FSF!).  Writing a portable
   compiler, even more so.  

There is LCC from princeton. The backends [that optimize as well
or better as GCC] are not available except by special educational
arrangement, but one can [for example] adapt arizona PO as a
backend...

here is the README.

    lcc is a retargetable compiler for C as defined by the ANSI Standard
    X3.159-1989. lcc is in production use at Princeton University and
    AT&T Bell Laboratories.
    
    The public distribution directory contains the following files.
    
    README  this file.
    
    install.{tex,ps}
            describes the distribution and gives installation
            instructions.  install.ps is the PostScript generated from
            the LaTeX input install.tex, which is also included in
            the distribution.
    
    lccfe-X.Y.tar.Z
            a compressed tar file for the `Front-end' distribution of
            version X.Y, e.g., lccfe-1.9.tar.Z.  This distribution
            includes the front end, the driver program, a demonstration
            VAX code generator, a `symbolic' code generator, a test
            suite, and user documentation.
    
    The distribution is available via `anonymous' ftp from princeton.edu
    (128.112.128.1) in the directory pub/lcc. Obtaining and extracting the
    distribution into its own directory is accomplished by the following
    commands. Replace `1.9' with the latest version, which is the only one
    typically available; versions like `1.9a' identify minor updates. As
    suggested, use your login as the password, and use ftp's binary
    transfer mode.
    
    mkdir lcc
    cd lcc
    ftp princeton.edu
    anonymous
    yourlogin
    cd pub/lcc
    binary
    get lccfe-1.9.tar.Z dist.tar.Z
    quit
    zcat dist.tar | tar xpof -
    rm dist.tar.Z

    Production code generators for the VAX, MIPS, and Motorola 68020 are
    available for research use to universities willing to execute a license
    agreement. Contact Chris Fraser (cwf@research.att.com) for details.
    These code generators are automatically generated from compact
    specifications, but neither the specifications nor their processor is
    available, only the generated code generators.
