[bug #63307] make 4.4 passes ignored SIGPIPE on to children

[Paul D. Smith]

Follow-up Comment #10, bug #63307 (project make):

I'm not sure how using a semaphore helps here.  We would still have to clean
up the semaphore with sem_unlink().

The main goal of that change was to allow our cleanup operations to proceed
even when SIGPIPE was found, and semaphores still need to be cleaned up.  To
that end it seems like the idea to use FATAL_SIG() (which already handles
SIG_IGN correctly) is the right one.

Sorry for not seeing that when the change was originally proposed.

Let me know if there is disagreement.
