Hrm.  Yeah.  The GNULIB vasprintf module has a lot of dependencies.
I've been plugging away at them slowly for awhile, maybe 6 months or a
year now as a background task, and I think the last stopper is the
GNULIB `error' module.  Basically, CVS's error function has diverged
considerably from the GNULIB version and any GNULIB module that uses the
GNULIB error might not send all the messages to the right place in
client/server mode.  I recently removed the error_exit function from
CVS's src/error.c to sync the API with GNULIB's error, but there is
still the issue of how to print - either the modules in lib will need to
know about the error function in src (the non-optimal solution - all the
other dependencies run in the other direction), or the GNULIB error
module will need to be rewritten to allow a function pointer to be
passed in and used in place of fprintf (since CVS's error function is
currently calling cvs_outerr to send output).

I'll probably get back to it sometime soon, but I wouldn't expect a
completion date sooner than a month since I have to get a few other
things finished first.  If someone else wants to take a look, they're
welcome to, but please let me know so we don't duplicate efforts.
