#if DEBUG vs #ifdef DEBUG

Igor,

Is it possible to convert the '#if DEBUG' line in vdtrace.c to an
'#ifdef DEBUG'? The former is abiguous if DEBUG is not defined,
or at least causes an error on the Metrowerks CodeWarrior compiler.

As far as I can tell, this is the only occurance of a bare #if.
All other code seems to use and #ifdef, but I noticed several
of the windows-ish makefiles mention or define DEBUG=0, so I'm
not sure how this is intended to interact.
