Log Message:
Pullup rev 1.56 (requested by bouyer in ticket #149)

Make wdc_channel->ch_flags volatile, and cast it to (void *) when used
in tsleep()/wakeup() to appease gcc. Otherwise, the ch_flags value may
be cached in a register in atabus_thread(), and when it sets the WDCF_TH_RUN
bit after tsleep() it may loose loose the changes made by an interrupt handler
or another thread.
