Changes upstream include:
* Added support for building on recent versions of Mac OS X
* Fixed warnings from autoconf/automake
* Fixed infinite loop in connection pool
* Fixed compiler warnings
* Fixed build dependency for make -jX
* Fixed check for Unicode driver
* Fixed issue calling SQLCancel from other thread
* Fixed SQLInstallDriverEx when driver is readonly
The "Fixed build dependency for make -jX" part is important, as parallel
builds (particularly with the GTK2 option on) normally fail with 3.52.8.
