"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:

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