#
# SYNOPSIS
#
# AX_PREFIX_CONFIG_H [(OUTPUT-HEADER [,PREFIX [,ORIG-HEADER]])]
#
# DESCRIPTION
#
# Generate an installable config.h.
#
# A package should not normally install its config.h as a system header,
# but if it must, this macro can be used to avoid namespace pollution by
# making a copy of config.h with a prefix added to all the macro names.
#
# Each "#define SOMEDEF" line of the configuration header has the given
# prefix added, in the same case as the first character of the macro name.
#
# 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.
#
# 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 output file 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) whose functionality depends on 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

# One issue with vendor 'install' (even GNU) is that you can't

# is unlikely to handle the host's binaries.
# Fortunately install-sh will honor a STRIPPROG variable, so we
# always use install-sh in "make install-strip", and initialize
# STRIPPROG with the value of the STRIP variable (set by the user).
