LoadLibrary during PROCESS_ATTACH

I am trying to debug Xilinx webpack version 5.1. If I understand things
right, the "ise" application crashed because it unloads a dll, but later
still accesses this dll.
This seems to happen, because during MODULE_InitDLL of the dll it calls a
Loadlibrary on itself. As MODULE_InitDLL sets WINE_MODREF_MARKER, and the
flow of execution in LoadLibrary checks for WINE_MODREF_MARKER before
incrementing the RefCount, the refcount gets wrong and the application
unloaded. Forcing the increment of RefCount in MODULE_LoadLibraryExA
unconditional of WINE_MODREF_MARKER makes the application continue.
Do we need the check for WINE_MODREF_MARKER in MODULE_LoadLibraryEx?
Do we still need MODULE_LoadLibraryEx at all?
