No need for foo="`bar`", foo=`bar` is fine.
Simplify ${foo} and ${1} into $foo and $1.
* acgeneral.m4 (ac_LF_and_DOT): Remove the double quotes.
* acspecific.m4 (AC_PROG_CC_C_O, AC_PROG_F77_C_O): Likewise.
* autoconf.sh: Likewise.
* autoheader.sh: Likewise.
* autoreconf.sh: Likewise.
* autoupdate.sh: Likewise.
* ifnames.sh: Remove all the code and messages related to
AC_MACRODIR, since ifnames is not related to macros in anyway.

Usage: ifnames [OPTION] ... [FILE] ...

|
|
|
Scan all of the C source FILES (or the standard input, if none are
|
|
given) and write to the standard output a sorted list of all the
|
|
identifiers that appear in those files in \`#if', \`#elif', \`#ifdef', or
|
|
\`#ifndef' directives. Print each identifier on a line, followed by a
|
|
space-separated list of the files in which that identifier occurs.

-v, --verbose verbosely report processing

-h, --help print this help, then exit

--version print version number, then exit
