# Create a function/macro that takes a series of named arguments. The call is
# similar to AC_DEFUN, but the setup of the function looks like this:
# BASIC_DEFUN_NAMED([MYFUNC], [FOO *BAR], [$@], [
# ... do something
# AC_MSG_NOTICE([Value of BAR is ARG_BAR])
# ])
# A star (*) in front of a named argument means that it is required and it's
# presence will be verified. To pass e.g. the first value as a normal indexed
# argument, use [m4_shift($@)] as the third argument instead of [$@]. These
# arguments are referenced in the function by their name prefixed by ARG_, e.g.
# "ARG_FOO".
#
# The generated function can be called like this:
# MYFUNC(FOO: [foo-val],
# BAR: [
# $ECHO hello world
# ])
# Note that the argument value must start on the same line as the argument name.
#
# Argument 1: Name of the function to define
# Argument 2: List of legal named arguments, with a * prefix for required arguments
# Argument 3: Argument array to treat as named, typically $@
# Argument 4: The main function body
