If we ever were to eliminate the procps.h header file, as discussed in the thread referenced below, then that would impair the current XTRA_PROCPS_DEBUG provisions. The only remaining way to verify result types would be to explicitly include that <proc/xtra-procps-debug.h>. So, this commit will once again enable the ./configure provision for defining the -DXTRA_PROCPS_DEBUG option.
