-Subject: [PATCH] configure.ac: search for dladdr only on libunwind
-
-The original configure.ac tries to check for dladdr, but it actually needs
-it only in case we have libunwind (which has a another section and checks for it
-too).
-This can fail the build on systems without dynamic linking support.
-Therefore, the dladdr check has to be performed only when checking libunwind.

-Subject: [PATCH] acinclude.m4: check if -latomic is needed
-
-On some cases, -latomic is needed for linking, and since the current
-acinclude.m4 checks only compilation we can sometimes miss the need for -latomic
-and the linking process will fail.
-Therefore, the AC_CHECK_IFELSE was replaced with AC_LINK_IFELSE. If the first
-try fails, we try to link again with -latomic and add LIBS="-latomic" in case we
-succeeded.
