+# SYNOPSIS
+#
+#   AX_SAVE_FLAGS([NAMESPACE])
+#
+# DESCRIPTION
+#
+#   Save common compilation flags into temporary variables.
+#
+#   Compilation flags includes: CPPFLAGS, CFLAGS, CXXFLAGS, LDFLAGS, LIBS,
+#   OBJCFLAGS.
+#
+#   By default these flags are saved to a global (empty) namespace, but user
+#   could specify a specific NAMESPACE to AX_SAVE_FLAGS macro and latter
+#   restore it by using AX_RESTORE_FLAGS(NAMESPACE).
+#
+#     AX_SAVE_FLAGS(mypackage)
+#     CPPFLAGS="-Imypackagespath ${CPPFLAGS}"
+#     dnl .. do some detection ...
