Can't build on Solaris 2.6

[Branko]

Hi,

I'm running into a problem building CVS head on Solaris 2.6,
using the mainline GCC. I'm doing a 3-stage bootstrap with
libstdc++-v3 used as as drop-in replacement for libstdc++.

The same thing happens with GCC 2.95.2 and with the 2.95.3
prerelease, and defining _GLIBCPP_BUGGY_FLOAT_COMPLEX doesn't
help.

Any ideas? Or is this a GCC bug?

    Thanks,
       Brane
