ifnames2.13 - print identifiers that a package uses in C preprocessor conditionals
!!SYNOPSIS


__ifnames2.13__ [[ __--help__ | __-h__ ] [[
__--macrodir=dir__ | __-m dir__ ] [[ __--version__
]
!!DESCRIPTION


__ifnames2.13__ can help when writing a
__configure.in__ for a software package. It prints the
identifiers that the package already uses in C preprocessor
conditionals. If a package has already been set up to have
some portability, this program can help you figure out what
its __configure__ needs to check for. It may help fill in
some gaps in a __configure.in__ generated by
__autoscan2.13__ (see
__autoscan2.13__(1)).


__ifnames2.13__ scans all of the C source files named on
the command line (or the standard input, if none are given)
and writes to the standard output a sorted list of all the
identifiers that appear in those files in __#if__,
__#elif__, __#ifdef__, or __#ifndef__ directives.
It prints each identifier on a line, followed by a
space-separated list of the files in which that identifier
occurs.


__ifnames2.13__ accepts the following
options:


__--help__


__-h__


Print a summary of the command line options and
exit.


__--macrodir=DIR__


__-m DIR__


Look for the installed macro files in directory DIR. You can
also set the __AC_MACRODIR__ environment variable to a
directory; this option overrides the environment
variable.


__--version__


Print the version number of Autoconf and exit.
