Install a misc/_config.h to hide all the defines that clutter the

built output.

This is also a step towards better checks for things like
__attribute__ or std::tr1.

# SYNOPSIS
#
# AX_PREFIX_CONFIG_H [(OUTPUT-HEADER [,PREFIX [,ORIG-HEADER]])]
#
# DESCRIPTION
#
# This is a new variant from ac_prefix_config_ this one will use a
# lowercase-prefix if the config-define was starting with a
# lowercase-char, e.g. "#define const", "#define restrict", or "#define
# off_t", (and this one can live in another directory, e.g.
# testpkg/config.h therefore I decided to move the output-header to be the
# first arg)
#
# takes the usual config.h generated header file; looks for each of the
# generated "#define SOMEDEF" lines, and prefixes the defined name (ie.
# makes it "#define PREFIX_SOMEDEF". The result is written to the output
# config.header file. The PREFIX is converted to uppercase for the
# conversions.
#
# Defaults:
#
# OUTPUT-HEADER = $PACKAGE-config.h
# PREFIX = $PACKAGE
# ORIG-HEADER, from AM_CONFIG_HEADER(config.h)
#
# Your configure.ac script should contain both macros in this order, and
# unlike the earlier variations of this prefix-macro it is okay to place
# the AX_PREFIX_CONFIG_H call before the AC_OUTPUT invokation.
#
# Example:
#
# AC_INIT(config.h.in) # config.h.in as created by "autoheader"
# AM_INIT_AUTOMAKE(testpkg, 0.1.1) # makes #undef VERSION and PACKAGE
# AM_CONFIG_HEADER(config.h) # prep config.h from config.h.in
# AX_PREFIX_CONFIG_H(mylib/_config.h) # prep mylib/_config.h from it..
# AC_MEMORY_H # makes "#undef NEED_MEMORY_H"
# AC_C_CONST_H # makes "#undef const"
# AC_OUTPUT(Makefile) # creates the "config.h" now
# # and also mylib/_config.h
#
# if the argument to AX_PREFIX_CONFIG_H would have been omitted then the
# default outputfile would have been called simply "testpkg-config.h", but
# even under the name "mylib/_config.h" it contains prefix-defines like
#
# #ifndef TESTPKG_VERSION
# #define TESTPKG_VERSION "0.1.1"
# #endif
# #ifndef TESTPKG_NEED_MEMORY_H
# #define TESTPKG_NEED_MEMORY_H 1
# #endif
# #ifndef _testpkg_const
# #define _testpkg_const _const
# #endif
#
# and this "mylib/_config.h" can be installed along with other
# header-files, which is most convenient when creating a shared library
# (that has some headers) where some functionality is dependent on the
# OS-features detected at compile-time. No need to invent some
# "mylib-confdefs.h.in" manually. :-)
#
# Note that some AC_DEFINEs that end up in the config.h file are actually
# self-referential - e.g. AC_C_INLINE, AC_C_CONST, and the AC_TYPE_OFF_T
# say that they "will define inline|const|off_t if the system does not do
# it by itself". You might want to clean up about these - consider an
# extra mylib/conf.h that reads something like:
#
# #include <mylib/_config.h>
# #ifndef _testpkg_const
# #define _testpkg_const const
# #endif
#
# and then start using _testpkg_const in the header files. That is also a
# good thing to differentiate whether some library-user has starting to
# take up with a different compiler, so perhaps it could read something
# like this:
#
# #ifdef _MSC_VER
# #include <mylib/_msvc.h>
# #else
# #include <mylib/_config.h>
# #endif
# #ifndef _testpkg_const
# #define _testpkg_const const
# #endif

dnl out a problem where `echo "\1"` results in a Control-A. The unix standard
dnl http://www.opengroup.org/onlinepubs/000095399/utilities/echo.html
dnl defines all backslash-sequences to be inherently non-portable asking
dnl for replacement mit printf. Some old systems had problems with that
dnl one either. However, the latest libtool (!) release does export an $ECHO
dnl (and $echo) that does the right thing - just one question is left: what
dnl was the first version to have it? Is it greater 2.58 ?
