[Ecls-list] fix for another slight problem using visual c++ toolkit 2003

[fBechmann at t-online.de]

the threading sample in ~\examples\threads\import_win32 was not linkable 
('cl : Command line error D2003 : missing source filename').
changing ecl-cc.bat as described below made it work:

    cl.exe -MD -Zi /link /nodefaultlib:libcmt /nodefaultlib:libc 
%CMDARGS% ~ecl.lib
    cl.exe %CMDARGS% -MD -Zi /link /nodefaultlib:libcmt 
/nodefaultlib:libc ~ecl.lib

Since ecl-cc.bat auto-generated, the real fix has to go somewhere else - 
but that's (currently) above my head.
