The attached patch is needed to build on AIX 7.1 with xlc V12.1 without
generating warnings about SIGPIPE being redefined (gzip tailor.h defines
SIGPIPE to 0 before /usr/include/signal.h redefines it to the proper
value, and other include files include signal.h). I think gzip works OK
even with the warnings, on this platform. Possibly the problem would
prevent gzip builds on other platforms, though. Normally I'd just
install this patch but we're so close to a release I thought I'd ask you
first.

Subject: [PATCH] gzip: port to AIX 7.1 + xlc V12.1
* inflate.c, unlzw.c, util.c: Include tailor.h after including any
system include file that might in turn include signal.h for the
first time, so that SIGPIPE is not #defined to 0 prematurely,
which clashes with signal.h's SIGPIPE.
