[Openmcl-devel] Running 32 bit ccl under win64.

The following is a know issue running the win32 version of ccl in a
win64 environment:

> wx86cl.exe
This application can't run under this OS version

I believe the source of the error is in lisp-kernel/thread-manager.c.
 In the function init_win32_ldt(), NtQueryInformationProcess is called
 in order to get the LDT_ENTRY of the current process.  

I don't know much about the context in which this happens, but the
attached test program (compiled to a win32 executable) indicates
NtQueryInformationProcess returns 0xc0000002 (STATUS_NOT_IMPLEMENTED)
in this circumstance. Is there a way to get around this in WoW64 (the
environment that runs 32 bit code under win64)?
