ai(and possibly ao) device support fails on a powerPC. In abDcmRecords.c the statements:

float value;
unsigned short *usvalue = (unsigned short *)&value;

must be replaced by

volatile float value;
volatile unsigned short *usvalue = (unsigned short *)&value;

This must be done in both get_float and in put_float.
