Subject: gtls: only call gnutls_transport_set_lowat with <gnutls-2.12.0
X-Git-Tag: upstream/7.37.1~3573
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=8036da870c5b413a83097b3486c58d13910a471a;p=platform%2Fupstream%2Fcurl.git

gtls: only call gnutls_transport_set_lowat with <gnutls-2.12.0

The default lowat level for gnutls-2.12* is set to zero to avoid
unnecessary system calls and the gnutls_transport_set_lowat function has
been totally removed in >=gnutls-3 which causes build failures.

Therefore, the function shouldn't be used except for versions that
require it, <gnutls-2.12.0.
