   1 /** @file
   2   Contains the empty version of the EBC Debugger hooks, to be used when
   3   compiling the regular EBC VM module.
   4   As debugging is not needed for the standard EBC VM, all calls are left empty.
   5
   6   The EBC Debugger defines its own version for these calls in EbdHooks.c.
