* Makefile.in (cygcheck.exe): Link against psapi.dll.

* bloda.cc: Change include section to work with Mingw64 headers.

	w32api headers.  Ditto for PSYSTEM_PROCESS_INFORMATION vs.
	PSYSTEM_PROCESSES.
	(system_module_list): New type to replace SYSTEM_MODULE_INFORMATION.
	Change usage throughout accordingly.
	(get_module_list): Fetch module list using PSAPI functions
	EnumDeviceDrivers and GetDeviceDriverBaseNameA.
	* cygcheck.cc (max): Define as __max if not defined already.
	(alloca): Only define if not defined already.
	(handle_unique_object_name): Use explicit sharing flags rather than
	FILE_SHARE_VALID_FLAGS which officially is only available in DDK
	headers.
	(PRODUCT_ULTIMATE_E): Only define if not defined already.
	* dump_setup.cc: Change include section to work with Mingw64 headers.
	(NtQueryAttributesFile): Drop NTOSAPI aka DECLSPEC_IMPORT.
