Details:

When compiling base on OpenSuse 12.1 I get the following warnings:

 Compiling file GSSocketStream.m ...
GSSocketStream.m: In function ‘-[GSTLS initWithInput:output:]’:
GSSocketStream.m:666:7: warning: ‘gnutls_protocol_set_priority’ is
deprecated (declared at /usr/include/gnutls/compat.h:285)
[-Wdeprecated-declarations]
GSSocketStream.m:673:7: warning: ‘gnutls_protocol_set_priority’ is
deprecated (declared at /usr/include/gnutls/compat.h:285)
[-Wdeprecated-declarations]
GSSocketStream.m:696:3: warning: implicit declaration of function
‘gnutls_transport_set_lowat’ [-Wimplicit-function-declaration]

And later the corresponding linker error:
Linking tool autogsdoc ...
../Source/./obj/libgnustep-base.so: undefined reference to
`gnutls_transport_set_lowat'
collect2: ld returned 1 exit status

This should be fixed by detecting the gnutls version in configure and using
#ifdef around that call as explained in this post:

We also should replace the other deprecated function call as explained here:

For now I will just switch off the usage of gnutls:
configure --disable-tls
