 151  *
 152  * Furthermore, we need to rearrange the main WINE_MODREF list to allow

 155  * 'hidden' dependencies created by modules calling LoadLibrary in their
 156  * attach notification routine.

 514  * The type of executable is a property that determines in which
 515  * subsystem an executable file runs under.
 516  *
 517  * Binary types returned:
 518  * SCS_32BIT_BINARY: A Win32 based application
 519  * SCS_DOS_BINARY: An MS-Dos based application
 520  * SCS_WOW_BINARY: A Win16 based application
 521  * SCS_PIF_BINARY: A PIF file that executes an MS-Dos based app
 522  * SCS_POSIX_BINARY: A POSIX based application ( Not implemented )
 523  * SCS_OS216_BINARY: A 16bit OS/2 based application
 524  *
 525  * Returns TRUE if the file is an executable in which case
 526  * the value pointed by lpBinaryType is set.
 527  * Returns FALSE if the file is not an executable or if the function fails.
 528  *
 529  * To do so it opens the file and reads in the header information
 530  * if the extended header information is not presend it will
 531  * assume that that the file is a DOS executable.
 532  * If the extended header information is present it will
 533  * determine if the file is an 16 or 32 bit Windows executable
 534  * by check the flags in the header.
