 149  *  from itself, but also via LoadLibrary from one of the called initialization
 150  *  routines.)
 151  *
 152  * Furthermore, we need to rearrange the main WINE_MODREF list to allow
 153  * the process *detach* notifications to be sent in the correct order.
 154  * This must not only take into account module dependencies, but also
 155  * 'hidden' dependencies created by modules calling LoadLibrary in their
 156  * attach notification routine.
 157  *
 158  * The strategy is rather simple: we move a WINE_MODREF to the head of the

 160  * detach notifications are called in the reverse of the sequence the attach
 161  * notifications *returned*.

 482  *           MODULE_GetBinaryType
 483  *
 484  * The GetBinaryType function determines whether a file is executable
 485  * or not and if it is it returns what type of executable it is.
 486  * The type of executable is a property that determines in which
 487  * subsystem an executable file runs under.
 488  *
 489  * Binary types returned:
 490  * SCS_32BIT_BINARY: A Win32 based application
 491  * SCS_DOS_BINARY: An MS-Dos based application
 492  * SCS_WOW_BINARY: A Win16 based application
 493  * SCS_PIF_BINARY: A PIF file that executes an MS-Dos based app
 494  * SCS_POSIX_BINARY: A POSIX based application ( Not implemented )
 495  * SCS_OS216_BINARY: A 16bit OS/2 based application
 496  *
 497  * Returns TRUE if the file is an executable in which case
 498  * the value pointed by lpBinaryType is set.
 499  * Returns FALSE if the file is not an executable or if the function fails.
 500  *
 501  * To do so it opens the file and reads in the header information
 502  * if the extended header information is not present it will
 503  * assume that the file is a DOS executable.
 504  * If the extended header information is present it will
 505  * determine if the file is a 16 or 32 bit Windows executable
 506  * by check the flags in the header.
 507  *
 508  * Note that .COM and .PIF files are only recognized by their
 509  * file name extension; but Windows does it the same way ...
