Any reason why macro definitions don't work in some elements such as a PANEL digits element? The following produces a "Number syntax" error:

Code:
#define A_MACRO_DEFINITION 0

PANEL* HUD = {
	digits(A_MACRO_DEFINITION , A_MACRO_DEFINITION, 0, *, 1, 1);
}

It seems this issue was also noticed by another user in this post.
