26 # There are a few dirty hacks below to avoid letting `AC_PROG_CC' be
27 # written in clear, in which case automake, when reading aclocal.m4,
28 # will think it sees a *use*, and therefore will trigger all it's
29 # C support machinery. Also note that it means that autoscan, seeing
30 # CC etc. in the Makefile, will ask for an AC_PROG_CC use...
35 # Autoconf 2.50 wants to disallow AM_ names. We explicitly allow

43 # call (pre autoconf-2.50), which is being phased out. PACKAGE

46 # We support both call styles for the transition. After
47 # the next Automake release, Autoconf can make the AC_INIT
48 # arguments mandatory, and then we can depend on a new Autoconf
49 # release and drop the old call support.
