AC_CONFIG_AUX_DIRS
Find the directory containing auxillery scripts for configure
Synopsis
AC_CONFIG_AUX_DIRS( [ directories to search ] )
Output Effect
Sets ac_config_guess to location of config.guess, ac_config_sub
to location of config.sub, ac_install_sh to the location of
install-sh or install.sh, and ac_configure to the location of a
Cygnus-style configure. Only install-sh is guaranteed to exist,
since the other scripts are needed only by some special macros.
The environment variable CONFIG_AUX_DIR, if set, overrides the
directories listed. This is an extension to the autoconf version of
this macro.
