Shouldn't these be defined with __attribute__ ((noreturn))?

Ugh.  I don't like this.  fork is slow enough and complicated enough
without adding this kind of workaround.  If this is a problem with
declaring an 'extern "C"' friend function then it should be fixable by
just making fork() a C++ function but exporting it as a "C" function
in cygwin.din.

Also, referring to a bug without explaining what the problem either in
the source code or the ChangeLog is a guaranteed way to cause confusion
tomorrow after a memory cache refresh.
