My configuration is probably atypical:

Using the Cygwin environment with the MSVC compiler. It is obvious
that the configure script was not set up for this as it passes $CC a
lot of gcc style compiler options to MS's cl.exe. Fortunately cl is
polite enough to print a diagnostic that it doesn't recognize the
option and proceed anyway. That said, this has worked successfully for
me in the past and I use it in preference to the nmake file you
provide because it lets me disable parts of curl that I don't want to
build. (Maybe nmake can do that also, but I am not very familiar with
that tool.)

Sorry, it looks like I was missing something. I always have avoided
looking in autoconf files and just grep through the generated
configure shell script. Reading configure.ac around line 227 it would
seem that my configuration probably lands me in the default case where
winsock_h and winsock2_h are set to "no" a priori.

Yes.

On further consideration this is probably also due to some a priori
judgment in configure.ac that winsock is not appropriate for my
environment ... and what I have found is some internal variable that
it used to track that judgment.

Yes, config.log excerpts provided below.

I guess this problem boils down to the configure script setting values
based on assumption instead of actual tests. I thought the entire
point of these scripts is to run the test and not rely on host
identifier tags, etc.

Thanks for the attention here and also for the quick reply.

Kind regards,
