* cygheap.cc (cygheap_init): Allocate space for sigaction array in cygheap.

* cygheap.h (cygheap_types): Add HEAP_SIGS.
* exceptions.cc (signal_fixup_after_exec): Remove from this file.
* pinfo.h (pinfo::getsig): Just return global_sigs array.
(pinfo::sigs): Delete.
* sigproc.cc (signal_fixup_after_exec): Move it here.
(global_sigs): New global array, moved from pinfo structure.
(sigalloc): New function.  Allocate global sigaction array here.
(proc_subproc): Remove copysigs call.  It's automatic now.
* include/sys/cygwin.h (PID_NOCLDSTOP): New value.
* signal.cc (sigaction): Set myself->PID_NODCLDSTOP when appropriate.
* sigproc.h (sigalloc): Declare.
* fnmatch.c (fnmatch): Use C90 parameters.
(rangematch): Ditto.
* fhandler.cc (fhandler_base::raw_read): Use right coercion to avoid a compiler
warning.
