Should be AC_SUBST([AM_CPPFLAGS], ['-I$(top_srcdir)/includes'])
or AC_SUBST([AM_CPPFLAGS], ['-I$(top_srcdir)/includes -I$(top_builddir)/includes'])
if you have built headers.
See the thread "RFC for new FAQ entry: Flag Variables Ordering" on the Automake lists to understand why redefining plain CPPFLAGS is wrong.
Thank you for the pointers!

(The above doesn't require this.)
Well, make distcheck is still failing, but not on every box I've tried it. I thought I would distill everything down to a simple 'hello, world' example (with a built header and a copy of stdio.h) which you can find at:
http://www.lawrence.edu/fast/lower/hello-0.5.tar.gz (it has to replicate there, but should be there by 20:30 GMT)
From that, configure.ac is:
# -*- Autoconf -*- # Process this file with autoconf to produce a configure script.
AC_INIT(hello,0.5) AM_INIT_AUTOMAKE(hello,0.5) AC_CANONICAL_HOST
# Checks for programs. AC_PROG_CC AC_PROG_INSTALL
AC_CREATE_STDINT_H([${srcdir}/includes/_stdint.h])AC_SUBST(AM_CPPFLAGS,['-I$(top_srcdir)/includes -I$(top_builddir)/includes'])
AC_CONFIG_HEADERS([config.h]) AC_CONFIG_FILES([Makefile src/Makefile]) AC_OUTPUT
...and, Makefile.am:
SUBDIRS = src EXTRA_DIST = reconf noinst_HEADERS = includes/stdio.h
...and, src/Makefile.am:
bin_PROGRAMS = hello hello_SOURCES = hello.c hello_CFLAGS = -Wall -pedantic
A make distcheck with this example fails on my home system with FC3 running on an AMD Athlon, but *succeeds* on an Intel box running an older Linux kernel, and older versions of autoconf/automake. I know that's a lot of variables. Perhaps I've still not learned something I should have, or am I running into some other problem?

Yes. However you'd better use noinst_HEADERS instead of EXTRA_DIST so that `make tags' and friends process the headers.
Again, thank you for the correction!
