Are we talking about the same bug? I submitted two close together.

#1543 affects the libmudflap build within gcc-4.1.2-final. I don't know
if that's soft-float or OABI specific, as I did not try any other
configuration. It does not affect gcc-4.2.1.

#1542 affects soft-float gcc-4.1.2 only: it needs the same patch as
I submitted for 4.2.1 earlier this week (and Ulf applied).
