STL commented:

Named modules can't emit macros, so either they need to be replaced with real language tech (e.g. INT_MIN => numeric_limits::min()) or a companion macro-only header needs to be provided.

Macros defined on the command-line can affect a module when it's built, but not macros defined within source files. The latter was always a risky idea for headers, but now it really needs to be avoided for modules.
