Use a macro GPID_FORMAT for the format to print GPid in (%p on Win32, %d

	* tests/child-test.c: Use a macro GPID_FORMAT for the format to
	print GPid in (%p on Win32, %d on Unix). Maybe configure.in should
	place that in glibconfig.h?

	Print verbose error message if CreateProcess() fails.

	Don't close the child handle until in the child watch callback.

	Don't try to run /bin/true on Win32. Run ipconfig instead (just to
	pick a program that should exist on all Window boxes).
