Hello,
That would break the ABI and require a soname change, afaiui.
I have the feeling that the discussion I started is an academic one
anyway. Nettle's public key library (libhogweed) uses and links against
libgmp, which is LGPLv3+. Therefore switching gnutls from gcrypt to
nettle would break GPLv2-compatibility (GPLv2 without the "or any
later version " clause). Oh dear.
