Standard `configure.ac' Layout
The order in which `configure.ac' calls the Autoconf macros is not
important, with a few exceptions. Every `configure.ac' must contain a
call to `AC_INIT' before the checks, and a call to `AC_OUTPUT' at the
end (*note Output::). Additionally, some macros rely on other macros
having been called first, because they check previously set values of
some variables to decide what to do. These macros are noted in the
individual descriptions (*note Existing Tests::), and they also warn
you when `configure' is created if they are called out of order.
To encourage consistency, here is a suggested order for calling the
Autoconf macros. Generally speaking, the things near the end of this
list are those that could depend on things earlier in it. For example,
library functions could be affected by types and libraries.
`AC_INIT(PACKAGE, VERSION, BUG-REPORT-ADDRESS)'
