The g++ compiler that is in current will crash (internal compiler error)
when trying to convert a va_arg() to a double (e.g. the attached code).
Both MozillaFirebird and KDE (qt3-libs) have code like this, so it's not
possible to compile these packages for sparc.  I raised gcc bug 13173 for
this, but it's not going to be fixed on the 3.3 branch.
