Subject: [SDL] [patch] fix building with DirectFB-0.9.25.1
another DirectFB release, another small bit of API breakage :)
this time around, DIKI_ALTGR has been removed and DIKI_ALT_R is supposed to be
used ... DIKI_ALT_R is not a new define, so there shouldnt be any need for
checking the DirectFB version ... it should work with older DirectFB's as
well
thanks to Sascha Schwarz for pointing this out on the Gentoo bugzilla:
