<matt@use.net>: * utils/cygcheck.cc (keyeprint): Move declaration before other functions so it could be used by all functions to report error messages. Add comment. (add_path): Check for NULL return from malloc. (find_on_path): Check initial uses of pointers for NULL. (rva_to_offset): Ditto. (init_paths): Add checking for return values of Win32 calls. (get_dword): Ditto. (get_word): Ditto. (dll_info): Ditto, also add NULL pointer checks. (scan_registry): Ditto. (check_keys): Ditto. (dump_sysinfo): Ditto. Add default case to switch. Add error reporting if GetVolumeInformation fails, except when it returns ERROR_NOT_READY. (track_down): Add checking for NULL pointers and return values of Win32 calls. (cygwin_info): Ditto. Correct small memory leak.
