-dnl @synopsis AC_CREATE_PREFIX_CONFIG_H [(OUTPUT-HEADER [,PREFIX [,ORIG-HEADER]])]
-dnl
-dnl this is a new variant from ac_prefix_config_
-dnl this one will use a lowercase-prefix if
-dnl the config-define was starting with a lowercase-char, e.g.
-dnl #define const or #define restrict or #define off_t
-dnl (and this one can live in another directory, e.g. testpkg/config.h
-dnl therefore I decided to move the output-header to be the first arg)
-dnl
-dnl takes the usual config.h generated header file; looks for each of
-dnl the generated "#define SOMEDEF" lines, and prefixes the defined name
-dnl (ie. makes it "#define PREFIX_SOMEDEF". The result is written to
-dnl the output config.header file. The PREFIX is converted to uppercase
-dnl for the conversions.
-dnl
-dnl default OUTPUT-HEADER = $PACKAGE-config.h
-dnl default PREFIX = $PACKAGE
-dnl default ORIG-HEADER, derived from OUTPUT-HEADER
-dnl if OUTPUT-HEADER has a "/", use the basename
-dnl if OUTPUT-HEADER has a "-", use the section after it.
-dnl otherwise, just config.h
-dnl
-dnl In most cases, the configure.in will contain a line saying
-dnl AC_CONFIG_HEADER(config.h)
-dnl somewhere *before* AC_OUTPUT and a simple line saying
-dnl AC_PREFIX_CONFIG_HEADER
-dnl somewhere *after* AC_OUTPUT.
-dnl
-dnl example:
-dnl AC_INIT(config.h.in) # config.h.in as created by "autoheader"
-dnl AM_INIT_AUTOMAKE(testpkg, 0.1.1) # "#undef VERSION" and "PACKAGE"
-dnl AM_CONFIG_HEADER(config.h) # in config.h.in
-dnl AC_MEMORY_H # "#undef NEED_MEMORY_H"
-dnl AC_C_CONST_H # "#undef const"
-dnl AC_OUTPUT(Makefile) # creates the "config.h" now
-dnl AC_CREATE_PREFIX_CONFIG_H # creates "testpkg-config.h"
-dnl and the resulting "testpkg-config.h" contains lines like
-dnl #ifndef TESTPKG_VERSION
-dnl #define TESTPKG_VERSION "0.1.1"
-dnl #endif
-dnl #ifndef TESTPKG_NEED_MEMORY_H
-dnl #define TESTPKG_NEED_MEMORY_H 1
-dnl #endif
-dnl #ifndef _testpkg_const
-dnl #define _testpkg_const const
-dnl #endif
-dnl
-dnl and this "testpkg-config.h" can be installed along with other
-dnl header-files, which is most convenient when creating a shared
-dnl library (that has some headers) where some functionality is
-dnl dependent on the OS-features detected at compile-time. No
-dnl need to invent some "testpkg-confdefs.h.in" manually. :-)
