!!DESCRIPTION |

|
| |
|
22 |
__ifnames2.13__ can help when writing a |
| |
|
23 |
__configure.in__ for a software package. It prints the |
| |
|
24 |
identifiers that the package already uses in C preprocessor |
| |
|
25 |
conditionals. If a package has already been set up to have |
| |
|
26 |
some portability, this program can help you figure out what |
| |
|
27 |
its __configure__ needs to check for. It may help fill in |
| |
|
28 |
some gaps in a __configure.in__ generated by |
| |
|
29 |
__autoscan2.13__ (see |
| 3 |
perry |

autoscan2.13(1)). |

__ifnames2.13__ scans all of the C source files named on |
| |
|
34 |
the command line (or the standard input, if none are given) |
| |
|
35 |
and writes to the standard output a sorted list of all the |
| |
|
36 |
identifiers that appear in those files in __#if__, |
| |
|
37 |
__#elif__, __#ifdef__, or __#ifndef__ directives. |
| |
|
38 |
It prints each identifier on a line, followed by a |
| |
|
39 |
space-separated list of the files in which that identifier |
| |
|
40 |
occurs. |
| |
|

__ifnames2.13__ accepts the following |
| |
|
44 |
options: |
| |
|
45 |
|
| |
|
46 |
|
| |
|
47 |
__--help__ |

Print a summary of the command line options and |
| |
|
54 |
exit. |

__--macrodir=DIR__ |

|

__-m DIR__ |
| |

|
| |
|

|
| |
|
63 |
Look for the installed macro files in directory DIR. You can |
| |
|
64 |
also set the __AC_MACRODIR__ environment variable to a |
| |
|
65 |
directory; this option overrides the environment |
| |
|
66 |
variable. |
