## are we using AC_CONFIG_HEADERS?
##    in http://www.gnu.org/software/autoconf/manual/autoconf.html#Writing-Autoconf-Input
## it is suggested that this is required to output config.h
## we are using AM_CONFIG_HEADER instead. How does this work?

# Process this file with autoconf to produce a configure script.
