Subject: Re:  internal compiler error gcc 4.5.1

I successfully built gcc on Solaris 10
using these versions of gmp/mpfr/mpc:

        gmp 4.3.2
        mpfr 2.4.2
        mpc 0.8.1

The instructions on the prerequisites.html page you reference below say
to use those versions "(or later)".  I'd recommend listing what
versions you have tested gcc with and say simply that other versions
haven't been tested.

I originally used the latest version of those three libraries:

        gmp 5.0.1
        mpfr 3.0.0
        mpc 0.8.2

Those three libraries _will_ work when building gcc on Linux or AIX--but
not Solaris (you get the "internal compiler error" message in the bug  
report I originally
submitted).

I  tried various combinations as well on Solaris (e.g. gmp 4.3.2, mpfr  
2.4.2, and mpc 0.8.2),
but only using the three earlier versions (gmp 4.3.2, mpfr 2.4.2, mpc  
0.8.1) worked.

Anyway, we have gcc working on all platforms now.

Thanks for all your help!
