Re: 64bit code generation for 3.1 on solaris?

[Andrey Petrov <and at genesyslab dot com>]

I did it using SUNWspro compiler on solaris2.7(shouldn't be much
difference) and uncommenting config.gcc lines already mentioned here.
The compiler used sun's as and ld, was able to rebuild itself,
I didn't try compare stages though.
I also tried with gnu-as/ld and it baciscly worked.
The target was sparc-sun-solaris2.7.  I do recommend this way
because you get compiler able to generate both 32 and 64 bit codes
with 32 bit default. I did it was only for c.
I used it for some time till I switched my primary platform.
The problem so far is that there is not enough support from gdb
(or at least I don't know how to set it up) so debugging
is problematic, espesially that dbx also doesn't understand
gcc's stabs. Besides that the impression is good and
it passed almost entire testsuite (a little more that 100 failed
tests from 14000+).
