This patch was already merged upstream and once bumping version of that
package this patch must be removed.

+Subject: [PATCH] Fix building in case of HAVE_EXPLICIT_BZERO
+
+Currently if toolchain has implementation of explicit_bzero() and so
+HAVE_EXPLICIT_BZERO gets defined during configuration compilation will
+fail that way:
+------------------------------------>8------------------------------
+utils.c: In function 'pure_memzero':
+utils.c:49:1: error: expected declaration or statement at end of input
+ }
+ ^
+------------------------------------>8------------------------------
+
+That happens because closing "#endif" is put 1 line below than really
+meant.
