Error when  complie the src on win32 use MSVC6:

//////////////////////////////////////////////////////////////////////////////////////////////

make[1]: Entering directory 
`/cygdrive/d/Devel/prolog/gprolog/gprolog-1.2.1/src/BipsPl'
gplc -c foreign.wam
\gplc3.asm:5: panic: internal instruction table corrupt: instruction code 0x84 
given

//////////////////////////////////////////////////////////////////////////////////////////////


Details:

I download gprolog-1.2.1 source code and want to use msvc6 build it(under 
cygwin of course).
I use these command:
1. ./configure --with-msvc --disable-sockets
2. make

At first, I get a error about "_stat" redefined error in file top_comp.c, when 
I remove "include <sys/stat.h>", this error gone.
Second, cl report that cpp_headers.c has a error (line. 151), so I change the 
source to :

stop_skip_comment:
#ifndef REMOVE_COMMENTS
         skip_comment=0;
#else
 skip_comment = skip_comment;
#endif

this error gone.

then another error occurs:
    In Makefile(src/EnginePl/) line. 59:
        $(TOP_LEVEL).h: headers.h cpp_headers
         D=`(cd ..;for i in *;do test -d $$i && X="$$X 
$(ROOT_DIR)/src/$$i";done;echo $$X)`; ./cpp_headers headers.h $(TOP_LEVEL).h $$D
    
    cl told me that it can`t locate the file headers.h, so I change it to :
    In Makefile(src/EnginePl/) line. 59:
        $(TOP_LEVEL).h: headers.h cpp_headers
         D=`(cd ..;for i in *;do test -d $$i && X="$$X 
$(ROOT_DIR)/src/$$i";done;echo $$X)`; ./cpp_headers 
$(ROOT_DIR)/src/EnginePl/headers.h $(TOP_LEVEL).h $$D

    error gone.

Then I get the error :
