Here is what happens, currently:

# gcc -v -threads
Reading specs from /usr/local/lib/gcc-lib/hppa1.1-hp-hpux10.20/3.0/specs
Configured with: ../configure --with-gnu-as --enable-shared
Thread model: single
gcc version 3.0 20010503 (prerelease)

This should be be `dce' and not `single' but this doesn't affect the
compilation problem.  When `-threads' is specified gthr.h includes
gthr-dce.h rather than gthr-single.h.  This defines __GTHREADS as 1 
and causes the thread code in eh_globals.cc to compile.

As far as I can tell, the identifiers eh_threads_initialize and
eh_context_key no longer exist anywhere.
