Fixed bug 978 Yann Leprince 2010-03-31 11:07:53 PDT Please add a #serial line as below to sdl.m4 and increase the serial number with each revision of this file. This allows using aclocal --install, thereby enabling automatic updating of sdl.m4 in SDL-based packages that distribute it. # serial 1 The complete documentation and rationale for #serial can be found in the Automake documentation: <http://www.gnu.org/software/automake/manual/html_node/Serials.html>.
