My believe is the standard de facto is Alan not gcc itself. Gcc is ANSI C
compliant with some GNU extensions. Usually you can put any ANSI C
constructs into the kernel.

gotos are part of ansi c. They just make for very ugly programs. The use of
gotos in C is disencouraged 99.99% of the time cause it makes for spagheti
code.

I never did Forth but i'm almost sure i'm glad the kernel was not written in
forth heehhe.
