Mysql now fully supports only OS X 10.9 and higher versions. The last OS X version that supported 32-bit binaries was OS X 10.6. Hence a decision was made to follow Apple's policy. Hence, MySQL no longer supports universal binary support nor does it support 32-bit binaries. Hence, this is not a bug. This is a policy in line with Apple's.
Description: configure.cmake has a few "IF(NOT APPLE)" and "IF(APPLE)" to support universal binaries. Similarly, config.h.cmake has several "#ifdef __APPLE__" to support universal binaries. In configure.cmake, MY_CHECK_TYPE_SIZE(time_t TIME_T) MY_CHECK_TYPE_SIZE("struct timespec" STRUCT_TIMESPEC) are not among them. CMake's function CHECK_TYPE_SIZE returns 0 for each since they have "arch-dependent size." This causes configure.cmake's function MY_CHECK_TYPE_SIZE to incorrectly deduce that they are not installed. Of course, this causes the resulting config.h to be incorrect. How to repeat: Compile MySQL on OS X as a universal binary (run cmake with -DCMAKE_OSX_ARCHITECTURES="x86_64;i386")
