The faq (question 1.12) states that the keyword "auto" is completely
useless.
However, it is necessary to forward declare a nested function (for
gcc...I'm not sure if this is gcc specific or a language issue.)

There is no such thing as a nested function in ISO C.

If gcc allows nested functions, that's its business. However, if it
requires "auto" to forwardly declare them, this is broken. They should
have chosen "static".
