Hi,

Does rule 7.1, "Octal constants (other than zero) and octal escape sequences shall not be used", apply to function-like macro arguments? For example:
Code:
#define MACRO(a)    XYZ_##a

int MACRO(01);

Is the '01' argument to MACRO() a violation of this rule?

No, because the concept of octal, hex etc constants doesn't exist until after pre-processing has been completed.
