The GNU Coding Standards (in section 5.1 "Formatting Your Source Code") 
call for this layout, and later mention that this is the only actual 
requirement; the other details are mere recommendations.

It ordinarily *should* apply, but there may be exceptions for very short 
programs.

In any case, putting the return type on a separate line is a consequence 
of the actual rule, which is the function names must begin in the first 
column, and the next unindented line must contain the opening brace of 
the function body.  The GNU Coding Standards explain that there are 
tools that use this pattern to identify functions, therefore all GNU 
code must adhere to it.

I am not really sure that this rule makes sense for Autoconf test 
programs, especially those that define *only* main() and no other functions.
