OK, this is a bug and the cause of all the rest of your woes.
could you please run the above in gdb, set a breakpoint in find_executable()
and see why it does not put the full patch into executable_name.
Apparently, GetModuleFileName puts "lisp.exe" into execname (execname.c:67).
Is that the case?

does this patch fix the problem?
