libg++ tests, tRandom fails on a Sony NWS-1830, also Sony diffs
#133

Environment: Sony NWS-1830 (m68030, BSD 4.3), NEWSOS 3.2, gcc 1.35.96
with three bugfixes from rms, g++.ytar.Z from yahi.stanford.edu as of
Aug 20, libg++ 1.35.1.

tRandom.c from the test directory fails with:

g++ -g -O -pipe -I../g++-include -I. -fstrength-reduce -fno-defer-pop -c  tRandom.cc
tRandom.cc: In function int main ():
tRandom.cc:82: type `LogNormal' is derived from private `Random'
tRandom.cc:85: type `Poisson' is derived from private `Random'

Also, here are the context diffs needed to use libg++ on a Sony news
machine.  I hope they can merged in the distribution:

(generic changes like the include/sys file bug omitted, except the
volatile abort thing which I don't remember seeing on the list.  Also,
you could probably use #if defined(sun) || defined(sony) for values.h;
the values were generated by hard-params.c from gcc but I had to
change them so I wouldn't get +Infinity and -Infinity into the
assembly file.  They were almost identical to those on the Sun, so I
copied MAX* from the sun values.)
