The very bad thing about inlined functions is that you have to put them in
header files (or a C file, but that's not the usual place). Then any
change to that function causes large recompilation. Then if you have a
compiler that doesn't support inlining, you lose.

There's nothing wrong with 'goto' so long as you use it properly.

Huh? If you're including a header for declarations you probably also need
some prototypes from it as well. If logically organized that is.

Yes, but you're compiling that 20k header 36 times in stock CircleMUD.
