We actually have AC_SYS_LARGEFILE in configure.ac already, which is supposed to append appropriate options to (slightly oddly) CC. Now, hostdisk.c is built with TARGET_CC instead; but TARGET_CC should be set to CC when building the emu target, if I'm reading this right, because it doesn't count as cross-compilation. Are you setting CC by hand? Could I see the output of configure? -- Colin Watson [[email protected]] _______________________________________________ Grub-devel mailing list [email protected] http://lists.gnu.org/mailman/listinfo/grub-devel
