The
-edebug compiler option defines the intrinsic macro
__FB_DEBUG__ to enable user debug code.
The intrinsic macro
__FB_DEBUG__ is set to non-zero (-1) if the option was specified, and set to zero (0) otherwise.
-edebug is automatically implied by the
-g option.
__FB_ERR__ can be used to determine in user source code if the
-edebug option was specified or implied on the command line.
