As far as I can see, this set of patches attempted to fix a minor
problem, but in doing so:
- added unnecessary dependencies on gnutls libraries
- broke the Windows builds (which use runtime linking for gnutls)
- broke all builds configured with "--without-gnutls"
I am happy for the original issue to be addressed, but only if all of
the issues listed above are addressed.
In particular, it must remain possible to build on a system that does
not have gnutls headers and libraries installed, or to disable gnutls
support even if the headers and libraries are present.
