Sparc version of gcc 2.95 can't catch from shared library throw

[David Barto <barto at visionpro dot com>]

I never saw a reply to this.

Gcc version - 2.95
Architecture - Sparc Ultra 10

the report from 'gcc -v' is
Reading specs from
/usr/local/gcc-295/lib/gcc-lib/sparc-sun-solaris2/2.95/specs
gcc version 2.95 19990728 (release)

This bug is not listed on the GCC bugs page. It is a simple
problem of having shared libraries on an Ultra throw an exception
and having the main program catch them.
