This makes no sense because it is enclosed in an #ifdef _MSC_VER
(python20_bcpp.lib was found!!! see your command line
"D:\PROGRAM FILES\LSS-ZOPE\BIN\PYTHON20\libs\python20_bcpp.lib" )

(The warnings are not a problem I think, because Borland C++ brings
more warnings than most other compilers.)
I think the problem (LIBS.OBJ) is the following part of the command line
C:\BORLAND\BCC55\BIN\ilink32.exe /Tpd /Gn /q /x
/Ld:\nusphere\mysql\lib\opt
==> "/LD:\PROGRAM FILES\LSS-ZOPE\BIN\PYTHON20\libs" <==
/L. c0d32
build\temp.win32-2.0\Release\_mysqlmodule.obj
d:\nusphere\mysql\lib\opt\mysqlclient.lib ,
build\lib.win32-2.0\_mysql.pyd
,, d:\nusphere\mysql\lib\opt\mysqlclient.lib
d:\nusphere\mysql\lib\opt\zlib.lib msvcrt libcmt wsock32 advapi32
"D:\PROGRAM FILES\LSS-ZOPE\BIN\PYTHON20\libs\python20_bcpp.lib" import32
cw32mt , build\temp.win32-2.0\Release\_mysql.def ,
Because of the quoting ilink might take this as an object filename.
(If it is not this, it might be the similar path name in the ilink32.cfg
file.)
It might be help to patch distutils/bcppcompiler.py as follows

I don't know if it helps, because I currently have no (Windows,Borland

computer available to test it. If it works send me a note, so we can
make it
an offical patch for distutils.
Kind regards
