+      Under the new changes, if your package fails its build with a message

+    <programlisting> 
+/usr/bin/ld: gpx-parser.o: undefined reference to symbol 'acos@@GLIBC_2.0'
+/usr/bin/ld: note: 'acos@@GLIBC_2.0' is defined in DSO /lib/libm.so.6 so try adding it to the linker command line
+    </programlisting>
+    <para>
+      Then the line that builds the specified .o needs to explicitly link libm.

+    <para>
+      <command>_builtin_stdarg_start</command> will return a undefined reference
