* dcrt0.cc (dll_crt0_0): Reorganize so that sigproc_init is called a little

later.  Add a comment.
* fork.cc (resume_child): Make void.
(frok::parent): Only zero pi when necessary.  Explicitly zero si.  Set
this_errno when child_copy fails.  Accommodate change to resume_child.
* sigproc.cc (sigalloc): Move global_sigs initialization here.
(sigproc_init): Move global_sigs.
(sig_send): Just check for flush signals once.
* wincap.h: Define supports_setconsolectrlhandler_null throughout.
* wincap.cc: Ditto.
