Cygwin_props have been invented to allow switching off the unique
installation keys in the first place, supposedly for debugging.
This never really was a good idea, after all we *want* the installations
to be independent and there's no good reason to break that, not even
for debugging purposes.
Other than that, cygwin_props were meant to be used for some other global
settings which never took place. There's just no good reason to tweak
the DLL binary invisibly where a setting could be done in a file or the
environment.
This patch removes the cygwin_props entirely, including the related
settings in cygcheck.
cygwin:
* cygprops.h: Remove file.
* globals.cc (cygwin_props): Remove.
* cygheap.cc (init_cygheap::init_installation_root): Drop removing
installation key.
utils:
* cygcheck.cc: Drop including cygprops.h. Remove now unused option
values.
(unique_object_name_opt): Remove.
(handle_unique_object_name): Remove function.
(usage): Remove text for unique-object-names options.
(longopts): Remove unique-object-names options.
(main): Drop handling unique-object-names options.
doc:
* utils.xml (cygcheck): Remove text for unique-object-names options.

* cygcheck.cc (load_cygwin): Only unload cygwin DLL if not running
under a debugger. Explain why.

(dump_sysinfo): Call RtlGetVersion rather than GetVersionEx to get
correct OS info even on Windows 8.1. Don't check return value since
RtlGetVersion never fails per MSDN. Move fetching kernel32 module
handle where it's really needed. Drop temporary comment added by
previous checkin.
if fetching OSVERSIONINFOEX failed. Drop code handling unsupported
platform IDs. Add code to tweak dwMinorVersion on Windows 8.1 if no
manifest is present.
(dumper.exe): Link against psapi.dll.
* cygcheck.cc (_WIN32_WINNT): Define as 0x0602.
(pInternetCloseHandle): Drop pointer.
(PRODUCT_UNLICENSED): Drop definition.
(PRODUCT_PROFESSIONAL_WMC): Ditto.
(package_grep): Delete code loading wininet functions dynamically, just
call functions directly.
as Windows Server 2012 and 2012 R2. Add missing commas in products
array to avoid crashes. Drop Windows NT4 and 2000 printouts. Just
call IsWow64Process, GetNativeSystemInfo, and GetDiskFreeSpaceEx
directly, rather than loading them dynamically, since they are exported
by all supported OS versions. Fix questionable type usage in call to
GetDiskFreeSpaceEx.
architecture message inline with stdout for clarity.
* path.cc (is_symlink): Always reset file pointer to beginning on exit.
(readlink): Assume that file pointer is set to the beginning.
* configure: Regenerate.
* Makefile.in: Remove references to mingw and w32api directories.
Use MINGW_CXX instead of mingw script to build MINGW_BINS.
Check for libiconv with $CC --print-file-name.
* cygcheck.cc: Use relative include paths for Cygwin headers.
* path.cc: Ditto.
* strace.cc: Ditto
* mingw: Remove.
* bloda.cc: Change include section to work with Mingw64 headers.
Include psapi.h. Use SystemProcessInformation instead of
SystemProcessesAndThreadsInformation throughout and add define for
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.
* strace.cc: Change include section to work with Mingw64 headers.
(alloca): Only define if not defined already.
option handling to use the same style throughout all Cygwin utils.
Throughout use program_invocation_short_name to refer to current
process name in Cygwin executables.
* utils.sgml: Align documentation to above change. Add missing
sections for getconf, ldd, and setmetamode.
* strace.cc (proc_child): Avoid compiler warning.
(dump_sysinfo): Ditto.
* loadlib.h (_load_sys_library): Mark as used, to avoid a compiler
warning.
* path.cc (oopt): Gurad with !FSTAB_ONLY to avoid a compiler warning.
(read_flags): Ditto.
Include throughout files using LoadLibrary function.
* cygcheck.cc (dump_sysinfo): Retrieve kernel32.dll handle via
GetModuleHandle, rather than using LoadLibrary.
* cygpath.cc (get_long_name): Ditto.
(do_sysfolders): Append .dll suffix in LoadLibrary call.
* ldh.cc (WinMain): Use LoadLibraryExW with DONT_RESOLVE_DLL_REFERENCES
to avoid loading malicious library code.
* locale.cc (print_locale_with_codeset): Change way to retrieve
kernel32.dll path.
(load_cygwin): Fetch cygwin DLL path and store in cygwin_dll_path.
* strace.cc: Full ditto.
* path.cc (read_mounts): First use the path stored in cygwin_dll_path,
if available. Then fall back to fetching own path. Add comment.
Drop printing warnings since they look funny in strace output.
to WCHAR win32 path, including long path conversion if necessary.
* cygcheck.cc: Use class wide_path throughout to call Win32 functions
taking potentially long filenames.
(display_error): Use snprintf rather than sprintf.
(display_error_fmt): Ditto.
(dump_sysinfo): Use FindFirstFileW/FindNextFileW.
* cygpath.cc: Use class wide_path throughout to call Win32 functions
taking potentially long filenames.
