When just calling ./configure on my box, I always ran into the same issue: In file included from /usr/include/nss3/pkcs11t.h:1780, from /usr/include/nss3/keythi.h:41, from /usr/include/nss3/keyt.h:41, from /usr/include/nss3/pk11pub.h:43, from libcacard/vcard_emul_nss.c:21: /usr/include/nss3/pkcs11n.h:365:26: error: "__GNUC_MINOR" is not defined
This is a bug in nss3. But why didn't configure bail out of the feature if it doesn't even compile? Because this really is just a warning, not an error. But configure builds its test program without -Werror, while we do build our sources with -Werror by default. Force the check to also use -Werror. This fixes the default build for me again.
