Bug report for egcs-1.1.1 on solaris2.6

[David Magerman <magerman at rentec dot com>]

It appears as though -mcpu=ultrasparc has a problem.  If I change the
code from 
  bool f(const foo &b) const { return (bar >= b.bar); }
to
  bool f(const foo &b) const { if (bar >= b.bar) return true; else return false; }
then things work fine.  And if I remove the -mcpu flag, or change it
to -mcpu=supersparc, it also works fine.

I whittled the bug down to a tiny example.  Here is the verbose output
and save-temps output to complete the bug report.
