-Subject: [PATCH] configure.ac: check if libatomic is needed
-
-gnutls source code uses the C++11 <atomic> functionality since
-https://github.com/gnutls/gnutls/commit/7978a733460f92b31033affd0e487c86d66c643d,
-which internally is implemented using the __atomic_*() gcc built-ins
-
-On certain architectures, the __atomic_*() built-ins are implemented in
-the libatomic library that comes with the rest of the gcc runtime. Due
-to this, code using <atomic> might need to link against libatomic,
-otherwise one hits build issues such as:
-
-../lib/.libs/libgnutls.so: undefined reference to `__atomic_fetch_sub_4'
-
-on an architecture like SPARC.
-
-To solve this, a configure.ac check is added to know if we need to
-link against libatomic or not. The library is also added to gnutls.pc.
-
-Fixes:
