Subject: GNU libc messages don't distinguish EPIPE and SIGPIPE
X-Mailer: VM 6.62 under Emacs 19.34.1

Package: libc6
Version:  2.1.2-1

GNU libc emits the same message ("Broken pipe" in the C locale) for
both EPIPE and SIGPIPE, but it would be useful if it distinguished
between the two.

I agree.

SIGPIPE is one of signals, and EPIPE is one of error numbers.  The
message "Broken pipe" is the result of SIGPIPE, and its error number.
I think there is no merit to distinguish them.  Moreover, how to
change the message between the two? It's difficult.

So I think it's not bug, it's not wishlist item. I close this bug.
