I don't think there is. Most probably you are using SO_RCVTIMEO to
setsockopt, so you get something different as errno than EAGAIN or
EINTR. This is like a BSD extension and I don't know if this can be
handled by gnutls in a portable way. As a quick hack you could make
a wrapper over recv() and return EINTR or EAGAIN when you get the
timeout errno code.
