* The type of executable is a property that determines which subsystem an

* values:
* SCS_32BIT_BINARY: A Win32 based application
* SCS_64BIT_BINARY: A Win64 based application
* SCS_DOS_BINARY: An MS-Dos based application

* SCS_POSIX_BINARY: A POSIX based application ( Not implemented )
* SCS_OS216_BINARY: A 16bit OS/2 based application
*
* To find the binary type, this function reads in the files header information.
* If extended header information is not present it will assume that the file
* is a DOS executable. If extended header information is present it will
* determine if the file is a 16, 32 or 64 bit Windows executable by checking the
* flags in the header.

* ".com" and ".pif" files are only recognized by their file name extension,
* as per native Windows.
