definitions that configure produces, including for WIN64. Still needs to be tested. 'lld' is not assured by the run-time DLLs and so GCC warns. Add TIFF_SIZE_T and TIFF_SIZE_FORMAT to provide a type definition and printf format specifier to deal with printing values of 'size_t' type. In particular, this was necessary for WIN64. Added a configure test for if the system headers provide 'optarg' (normal case) and block out the many explicit 'extern' statements in the utilities. This was found to be necessary under Windows when getopt is in a DLL and the symbols are already imported with dllimport via standard header files.
