That's too much for me. I'll wait until ghc-6.8 (or ghc-6.10) can be
bootstrapped from C-sources.

One (maybe minor) problem under Solaris (and MacOS I think) is that
already configure decides by default to be under i386, i.e. in 32bit
mode (through "arch" or "uname -p").

Only extending the call to gcc with "-m64" will create 64Bit code.

You have done it under Linux. Maybe you find an easy path from 32Bit to
64Bit under Linux that one may also try under Solaris and Macs.
