* child_info.h: Bump magic number.
(class child_info): Add an element. * cygheap.cc (init_cheap): Allocate cygwin heap in shared memory area. (cygheap_fixup_in_child): Map cygwin heap, passed from parent via shared memory into correct address. (cygheap_setup_for_child): New function. * cygheap.h: Declare new functions. * dcrt0.cc (dll_crt0_1): Accomodate new cygheap_fixup_in_child arguments. Avoid protecting subproc_ready unless it is spawn/nowait. * fork.cc (fork_parent): Use new cygheap_setup_for_child function to setup cygwin heap info. Close passed cygheap shared memory handle. * spawn.cc (spawn_guts): Ditto. Also, reorganize to avoid synchronization between parent and child in non-P_OVERLAY case. * sigproc.cc (wait_sig): Only signal subproc_ready when execing.
