Hi, It seems that in include/asm-i386/param.h the "#include " should be inside the #ifdef __KERNEL__, as it is done in asm-ia64. Some applications cannot compile/work correctly whithout this patch. For example busybox defines for itself CONFIG_TR (related to the tr program), which is unfortunately undefined when including sys/param.h, which includes linux/config.h (CONFIG_TR is the config for token ring). Can you consider the following patch ? Thanks, Olivier
