Multiline macro cleanup

This is mostly a cosmetic patch.

The purpose of wrapping a multi-line macro in a do { } while(0) is to
make the macro usable as a regular statement, not a compound statement.

When the while(0) is terminated with a semicolon, the do { } while(0);
block becomes a compound statement again.
