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: autoreconf [OPTION] ... [TEMPLATE-FILE]
|
|
|
|
Run \`autoconf' (and \`autoheader' and \`automake', where appropriate)
|
|
repeatedly to remake the Autoconf \`configure' scripts and
|
|
configuration header templates in the directory tree rooted at the
|
|
current directory. By default, it only remakes those files that are
|
|
older than their predecessors. If you install a new version of
|
|
Autoconf, running \`autoreconf' remakes all of the files by giving it
|
|
the \`--force' option.
|
|
|
|
-m, --macrodir=DIR directory storing macro files
|
|
-l, --localdir=DIR directory storing \`aclocal.m4' and \`acconfig.h'
|
|
-f, --force consider every files are obsolete
|
|
-v, --verbose verbosely report processing
|
|
-h, --help print this help, then exit
|
|
--version print version number, then exit
|
|
|
|
The following options are passed to \`automake':
|
|
--cygnus assume program is part of Cygnus-style tree
|
|
--foreign set strictness to foreign
|
|
--gnits set strictness to gnits
|
|
--gnu set strictness to gnu
|
|
-i, --include-deps include generated dependencies in Makefile.in
|
|
|
|
Report bugs to <bug-autoconf@gnu.org>."
