I have to disagree.  From aclocal(1) man page:

"The  contents of acinclude.m4, if it exists, are also automatically
included in aclocal.m4.  This is useful for incorporating local macros
into configure."

and acinclude.m4 is the file which is patched.  If you look at the
comments at the top of acinclude.m4 you will clearly see that it was
originally written by Ian Piumurta.
