This file shows the problem. I requires no includes.
This has been fixed in 3.0.3 AFAIK, but we switched to gcc 3.1 in rawhide, so gcc3 won't be updated for this. |

See <URL:http://bugzilla.redhat.com/bugzilla/> for instructions. Expected Results: Compilation without errors or warnings. Additional info: All compiler flags are essential to reproduce the problem. bug.c is a result of preprocessing and simplifying of the 8193too driver.
