Native build hangs

["Michael L. Hitch" <mhitch%lightning.msu.montana.edu@localhost>]

The problem of native builds hanging in src/lib/libm/complex should
be fixed in -current now.  I will be requesting a pullup to netbsd-5
soon.

This was caused by use of a bad floating point number in catan.c (it
has a hard-coded IEEE value) plus the addition of a SIGFPE handler
in lint (added to make it not rely on IEEE floating point) plus the
trap handler on the vax leaving the return address from the signal
handler pointing to the instruction that caused the floating point
overflow fault.  This resulted in a loop calling the signal handler.
