"config.gcc sun3" for both, test10 of the test suite gives an error.

On Sun3's, the file RNG.cc *must* be compiled with the -ffloat-store 
option. A comment in Dirk Grunwald's RNG.cc code explains why.
My apologies for not mentioning this anywhere in the installation
instructions.

While I am at it, here are the other known bugs in libg++-1.34.0:

1. CursesWindow (test23) fails on Sun3's and Sun4's under X-windows,
but not under terminal emulation or remote logins.  I have not yet
discovered why.

2. I incorrectly modified etc/Patmain.cc. Here are the diffs:
R>diff -2rcN Patmain.cc~ Patmain.cc
*** Patmain.cc~	Thu Mar  9 06:51:52 1989
--- Patmain.cc	Fri Mar 10 06:39:50 1989

     else {
        if ( ! freopen ( argv [ 1 ], "r", stdin ) ) {
!          perror ( argv [ 0 ] ), return;
        }
        Patricia_Trie Trie;

     else {
        if ( ! freopen ( argv [ 1 ], "r", stdin ) ) {

        }
        Patricia_Trie Trie;

        fclose ( stdin );
        if ( ! freopen ( argv [ 2 ], "r", stdin ) ) {

        }

        if ( ! freopen ( argv [ 2 ], "r", stdin ) ) {
!          perror ( argv [ 0 ] ); return;
        }

3. etc/gperf/stderr.cc contains improper intitializations. Here are the diffs: 

R>diff -2rcN stderr.cc~ stderr.cc
*** stderr.cc~	Fri Mar  3 06:11:38 1989
