This sounds like a problem with the Tru64 implementation of signals
and/or SIG_RESTART.

I have two suggestions: first, try using the 3.81beta1 release
(http://mad-scientist.us/make/make-3.81beta1.tar.bz2).

If that doesn't help, try reconfiguring GNU make with the
--disable-job-server flag and rebuild it, and see if that helps.
