CVS commit: basesrc/usr.bin/make

[Andreas Gustafsson <gson%netbsd.org@localhost>]

Module Name:    basesrc
Committed By:   gson
Date:           Sat Nov 16 22:22:24 UTC 2002

Modified Files:
        basesrc/usr.bin/make: job.c job.h

Log Message:
Fixed race condition that would cause make -j to pause for five
seconds if a SIGCHLD arrived while make was not blocked in poll(),
by making the SIGCHLD handler write to a pipe included in the poll.
Avoided the need to implement a duplicate fix for the USE_SELECT case
by emulating poll() in terms of select() when USE_SELECT is defined.
Fixes bin/18895.
