# grep -c '^[^;]*(defmacro' $CC_RELFILESEL | sort -t: -nk2

gives this as a result:

cc-align.el:0
cc-cmds.el:0
cc-compat.el:0
cc-menus.el:0
cc-styles.el:0
cc-subword.el:0
cc-awk.el:1
cc-vars.el:1
cc-mode.el:2
cc-langs.el:3
cc-fonts.el:4
cc-bytecomp.el:16
cc-engine.el:22
cc-defs.el:43

, so pretty much all the macros are in 2 files.  (cc-bytecomp.el
only contains compile-time macros which won't mess other things up
much).

On or two macros could be moved from cc-mode.el to cc-defs.el, but it
seems scarcely worth the bother.  I think all (or very nearly all) the
others are used locally in the files that define them and don't depend
much on other files, so it would degrade maintainability to move them.
cc-defs.el is the home of CC Mode's "general" macros.

I think the problem here was that I changed a macro in cc-defs.el and
added two new c-lang-setvar's into cc-langs.el.  These made
recompilation of cc-engine.el necessary.
