Subject: [PATCH 06/10] Change cv_forcedMemPeriodic to uint8_t as bool is
 invalid
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

GCC6 throws the following error:
operand type ‘bool*’ is incompatible with argument 1 of ‘__sync_fetch_and_and’

GCC documents that bool is invalid for __sync builtins over at:
https://gcc.gnu.org/onlinedocs/gcc/_005f_005fsync-Builtins.html#g_t_005f_005fsync-Builtins
" GCC allows any scalar type that is 1, 2, 4 or 8 bytes in size other than the C type _Bool or the C++ type bool"
