Problem bootstrapping gcc-3.1-20020510 on sparc-sun-solaris2.8

["Rude, Randy [Cont]" <Randy dot Rude at gdcanada dot com>]

There appears to be a dependency problem for gnat1.  The gmake bootstrap is
ok (with the long filenames and long-long patches in place) but gmake
gnatlib_and_tools fails with:

Is this a problem with my build environment?  I found the missing symbol
defined in libgcc but I'm puzzled that no one else seems to have encountered
this one.
