I tried the previous patch you had sent some time ago (the
version with 'conf$[$]'). But this didn't work for Bill's
cl.exe. The generated Makefile still uses -c and -o on the same
command line. I had verified that the new code is in configure.

The generated config.log says

        configure:4747: checking whether cl and cc understand -c and -o together
        configure:4779: cl -c conftest.c -o conf1504.obj >&5
        Microsoft (R) 32-bit C/C++ Optimizing Compiler Version 13.10.3077 for 
80x86

        conftest.c
        configure:4782: $? = 0
        configure:4829: result: no

Yet the generated Makefile contains

hello-main.obj: main.c
        source='main.c' object='hello-main.obj' libtool=no \
        DEPDIR=$(DEPDIR) $(CCDEPMODE) $(depcomp) \
        $(CC) $(DEFS) $(DEFAULT_INCLUDES) $(INCLUDES) $(hello_CPPFLAGS) \
        $(CPPFLAGS) $(AM_CFLAGS) $(CFLAGS) -c -o hello-main.obj `IFS=:; 
x=':$(VPATH)'; for d in $$x; do test -n $$d && d=$$d/; test -f $$d'main.c' && 
$(CYGPATH_W) $$d && break; done`'main.c'

The object file is created, but it is not called "hello-main.obj".

Can I post a testcase here? It would be about 100KByte, so I
should ask first. (Its so big, because it includes the
configure script and the Makefile generated on Windows.)
