Hello,

I've had problems building VM. Apparently the file 
$SOURCE_ROOT/platforms/unix/src/vm/debug.c and debug.h were adjusted to 
handle a Mac OS X problem regarding to dprintf. In file debug.c it is 
necessary to include stdlib.h to handle abort(). But then, dprintf is 
polymorphic and is not properly handled:

gcc -g -O2 -fomit-frame-pointer -DLSB_FIRST=1  -DHAVE_CONFIG_H

Problem code at debug.h is:
