dnl AM_PATH_GENGAMENG(MIN-VERSION)
dnl
dnl Tests for gengameng, and defines GENGAMENG_PREFIX, GENGAMENG_CFLAGS
dnl and GENGAMENG_LIBS, as well as GENGAMENG_CONFIG, which is the full name
dnl of the gengameng-config script.
dnl All of these variables are submitted to AC_SUBST().
dnl Also tries to link a test program with gengameng.
dnl Calls AC_MSG_ERROR() on failure.
dnl Offers the option --with-gengameng-config=X. Default is to search $PATH.
dnl
dnl Receives minimal version number to require as the argument.
dnl Example: AM_PATH_GENGAMENG(4.0)
