It actually is. gcc gives an error when it's not available. The preprocessor is not C, so it's a slightly different rule.
I committed the build fix patch below.
thanks,

An old version of PA doesn't define this macro, and gives a build error.

It seem that there is no way to use "handle_underrun=1" anymore ?
attach a test program which test the playback/capture position
The result seem avail of "pulse" device never reach buffer_size and the accuracy of the pointer of pulse device depend on the period time and it is not as accurate as than those of "hw" and "plug:dmix"
