This seems wrong when the typedef is just being used in another declaration with the mode attribute, as opposed to being defined using the mode attribute. E.g. the following test is valid and accepted before the patch, but wrongly rejected after the patch because the typedef has had its type changed. typedef int I; int x; I y __attribute__ ((mode(QI))); extern I x; -- Joseph S.
