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

[Dmitry Goncharov]

Follow-up Comment #2, bug #63307 (project make):

Is it useful to restore sigpipe before spawning children? Is that not good
enough to have sigpipe disposition set to default for children?
There are signals for which it is important to preseve the disposition,
notably sighup for nohup, but not sigpipe.
Unix programs assume that sigpipe is set to the default disposition. Is there
a program which misbehaves if make sets sigpipe to the default?
With these considerations in mind i suggest the patch in the attachment.
