Hello, In /usr/xsrc/xfree/xc/programs/Xserver/include/compile.h, #ifndef __NetBSD__ #ifndef MAP_FAILED #define MAP_FAILED ((void *)-1) #endif #endif but complains a few lines after that MAP_FAILED is not defined... Should I change the first line above by #ifdef __NetBSD__ ? Perhaps one of you know what's wrong here ? Thank you -- Samuel.
