Problems compiling libstd++-2.90.3 on Solaris 2.6

[Dave Wreski <dave@nic.com>]

Hi all.  I'm using gcc-2.7.2.3 on Solaris/SPARC and having trouble
compiling libstdc++.  I'd eventually like to use it to compile KDE for
Solaris.  Is there a later/different version I should be using for this
purpose?

Thanks,
Dave Wreski
