  I attempted to build gmp-4.2.1-rc.tar.bz2 on AIX 5.3 with the IBM C
  compiler v7.0:
    $ cd /opt/build/chin
    $ gtar jxf gmp-4.2.1-rc.tar.bz2
    $ cd gmp-4.2.1-rc
    $ ./configure CC=xlc CFLAGS="-O2 -qro -qroconst -qmaxmem=-1 -qarch=ppc" \

    LDFLAGS="-Wl,-brtl" ABI=32 M4=/opt/TWWfsw/m4/bin/gm4 --enable-shared \
    --enable-static --disable-dependency-tracking
    ...
    $ gmake
    ...

  I've attached a copy of mpn/tmp-mode1o.s.
  
A model for a bug report.  :-)

The used assembly code is modelled after the gcc output (from a now
obsolete gcc version).  It seems it is rejected by IBM's xlc compiler.

With the change below, I get clean builds with both xlc and gcc, using
it.  Please test the patch and report the outcome.
