Hi, Commit 1f24725c9a0b09e7a42ee18f2bb4c0fbac581b8f removed `GNUTLS_A_UNKNOWN_SRP_USERNAME' and `GNUTLS_A_MISSING_SRP_USERNAME', thereby breaking the Guile bindings. I just committed a tiny patch that fixes it. http://git.sv.gnu.org/gitweb/?p=gnutls.git;a=commitdiff;h=2518a0dc871d877bf3269cda498ae1831ff22fb8 Thanks, Ludovic.
