I don't think we should export or even use struct, union, or enum tags.
All structs, unions and enums should be without tag, and should be referred
to by a typedef'd name. The only exceptions should be structs etc whose
declarations we have no control over, e.g. struct stat.

I think putting _s or _p after variable names to denote static or pointer
is a bad idea.

The indentations on the if statements in 5.1 and 5.2.1 are inconsistent.
