Subject: (_AC_OUTPUT_CONFIG_STATUS): Use a here document to output the default
X-Git-Tag: AUTOCONF-2.59c~308
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c4f2d3d01eb288148ff99f1713df9b907601f0fb;p=thirdparty%2Fautoconf.git

(_AC_OUTPUT_CONFIG_STATUS): Use a here document to output the default
   config_* lists to config.status.
   Don't recognize option --file, if the functionality is not there.
   Likewise for --header; moreover, recognize --he and --h as shortcuts
   for --help in that case.
