Documentation states that AC_*_IFELSE has to use AC_LANG_SOURCE or friends in order to generate the source code to compile. AC_LINK_IFELSE already handles this, thus convert AC_COMPILE_IFELSE to silence the final autoconf warnings. Signed-off-by: Emil Velikov <emil.l.velikov@xxxxxxxxx> --- While this patch is not strictly speaking necessary for the full/correct build of libdrm, it cuts down the configure'n'compile warnings to five. With the remaining being caused due to type conversion within exynos(4) and freedreno/kgsl(1). I planning to leave those to someone more aware of the respective codebase :) Cheers, Emil P.S.
