Comment (by simonmar):

 Ah, that's interesting.  Yes the RTS does have a way to allocate
 executable memory, but it appears that the Win32 object linker isn't using
 it: line 1379 of rts/Linker.c:

 {{{
    oc->image = stgMallocBytes(oc->fileSize + misalignment,
 "loadObj(image)");
 }}}

 Could you try changing this to

 {{{
    oc->image = allocateExec(oc->fileSize + misalignment);
 }}}

 and see if that helps?
