 Ouch -- there used to be such a bug in the past, but it was fixed on Aug
6th, 2003.  Please update indeed -- your snapshot is severly old and there
have been plenty updates since then, so chances are you may struggle with
problems that have been dealt with elsewhere, too.  Please use the CVS, of

 I've stripped the preceding unrelated entry code.  The "_int" alternate
entry points to exception handlers were merged from 2.4 on Jan 3th (only
handle_fpe_int is actually needed, for R3k-class CPUs, as they handle the
FP error as an ordinary interrupt).
