Why are you building with --enable-threads=solaris in the first place?
Just omit --enable-threads (defaulting to posix); the implementation of
both on Solaris 2 is the same, anyway. It is beyond me why anyone would
want to program to the old UI Threads interface.
That said, I'm testing the obvious fix:
Index: gcc/gthr-solaris.h

I've now idea what other problems with --enable-threads=solaris might
exist, though. This isn't regularly tested.
