Just to clarify, goto is part of the standard C language, not a gcc
extension. gcc does provide computed gotos, though, which standard C
lacks. (Whether this is a good thing is a can of worms I choose not
to open.)

[You can get the effect of a computed goto in standard C using a
switch full of goto's, and any decent compiler should generate about
the same code as for an explicit computed goto, so I don't see that
particular wart as a major one. -John]
