+Subject: [PATCH] Define GCC_VERSION macro to cover upto gcc-5
+
+Current check is limited to gcc 4 with minor versions
+but when we use gcc 5.1, then minor version check fails
+with current setup and we end up with build errors like
+
+| In file included from bn_div.c:62:0:

+| bn_lcl.h:311:9: error: impossible constraint in 'asm'
