Is building with cl.exe (Visual Studio) supposed to work? I remember some
discussion on the mailing list, but I don't know whether compilation was made to
actually work. When I try building with CL, I get a bunch of errors, many
apparently unrelated to my changes. For example,

emacs.c
c:\users\dancol\software\emacs\cyg.w32test\src\lisp.h(336) : error C2065: 'PTRDI
FF_MIN' : undeclared identifier
c:\users\dancol\software\emacs\cyg.w32test\src\lisp.h(336) : error C2099: initia
lizer is not a constant
c:\users\dancol\software\emacs\cyg.w32test\src\lisp.h(2375) : error C2065: 'PTRD
IFF_MIN' : undeclared identifier
