Browse Source 
(path_conv::iscygexec32): Drop unused inline function.
	(path_conv::iscygexec64): Ditto.
	(path_conv::set_cygexec): Remove unnecessary setting of PATH_64BITEXEC.
	* spawn.cc (child_info_spawn::worker): Disable setting of
	STARTUPINFOW::lpReserved2 and STARTUPINFOW::cbReserved2 for non-Cygwin
	child processes.  Explain why.
