I am under the impression that most of the wide
character support functions should not be needed.
They would only be getting referenced from
lib/regcomp.c or lib/fnmatch.c or
lib/fnmatch_loop.c and the equivalent code for all
of the functions provided by those files should be
getting built in the windows-NT directory.

Sure.

The lib/* functions are presumed to be
compatibility functions that will work reasonably
portably when the operating system does not
provide the function needed. I suppose it is
possible we are yet missing some GNULIB
compatibility functions, but I would not have
expected wide character manipulation routines to
be among their number as I would not have expected
them to be needed.

Sadly, this file will not have been included for
the general readers of the bug-cvs mailing list as
it seems that attachments are stripped by the
mailing list software.

It seems that regex.obj is being created with a
_btowc reference out of _re_compile_fastmap_iter

referenced in function _re_compile_fastmap_iter

I am given to understand that windows <wchar.h> does support mbrtowc().

Does your system have an mbrtowc and mbrlen

  http://msdn2.microsoft.com/en-us/library/5wazc5ys(VS.80).aspx

seems to indicate that it should have one somewhere...

Hmmm... a branch tag will need to open and write
all of the ,v files in the repository and this
operation will be happening on the server.

As the windows binary for 1.12.12 and 1.12.13 is a
client-only binary, I know that some other cvs
server is doing the taggging. You should be able
to take a look at the time it takes for cvs to do
the job on the server to see how much is related
to client-side problems and how much is the server
side.
