Well... doesn't look much better to me.
Too little to be the reason for upgrading rpm or preprocessing specs
somewhere else whenever I have to build some packages from post-Ra
resources...

Lack of nested comments was more disturbing.

Maybe implementing %ifdef and %ifndef (to be used instead of
0%{?...:1} and 0%{!?...:1}) would be worth... but it would make many
specs incompatible with rpm from Ra :/
