Re: 1.8.1 config fails, but gmp passed its tests.

[Hugh Sasse]

I have explored this a little further.  If I 
  export CC=gcc\ -v
I get no more information out of this really.  It is skipping those
libraries, but I can't see why.  GNU ld seems to lack a verbose option.
Running
  configure --without-gnu-ld
doesn't help -- configure sees that GCC uses /usr/local/bin/ld and
proceeds to use that.  At the moment I have no reason to assert that
it shouldn't use GNU ld, only that since GNU ld insists on skipping
those libraries it seems worth trying to get Sun's ld in on the act.

Can anyone advise me how to proceed, please?
        Thank you,
        Hugh
