* Source/GSFileHandle.m:
* Source/NSMessagePort.m:
* Source/NSSocketPort.m: Only ignore SIGPIPE if there is no
handler set up for it. If some other code has set up a handler
before GNUstep code is used, we should not be overriding that
handler as the external code may later depend on receiving the
signal. Many thanks to Nicola for the investigative work
leading up to this realisation.

* Source/NSObject.m: Do not include signal.h.
