Subject: RETBUG flag in building cfront version 1.2

Does anybody know whether I can undefine RETBUG when building cfront 1.2
for the HP9000/835?

I tried some tests by hand and found that this _plain_silly business costs
a lot of time ( apparently the HP compiler optimizer pass does not see that
the whole thing is bogus ) when running on an HP9000/835. However I am
somewhat scared just turning that flag off, since I don't understand this
bug that the RETBUG flag is a workaround for.

Also has anybody using cfront 1.2 on the HP9000/835 gotten the form()
library call to work properly? Apparently its assumptions about stack
layout don't hold on the HP9000/835 so that things like

double a = 1.2345;
cout << form( "%F", a ) << "\n";

just print garbage.

Any suggestions/help is much appreciated!

Peter
