The following code complains of too many initializers in aggregate
initialization under g++/gcc and not on other systems (Silicon
Graphics, Turbo C++).  Removing the union allows the initialization
to succeed.

I scanned the GCC info under emacs on the system where the software is
installed and did not see this mentioned.  The output from g++ -v bug.cc
is:
