Andy,

I tried the make with the stock 2.6.2 kernel (from kernel.org) without
error.  The offending code:


        /* sysfs */
        #if LINUX_VERSION_CODE < KERNEL_VERSION(2, 6, 2)
        struct class_simple;
        static inline void class_simple_device_add(struct class_simple
        *class, int devnum, ...) { return; }
        static inline void class_simple_device_remove(int devnum) {
        return; }
        #endif


probably assumes kernel versions < 2.6.2 needs these definitions, but
maybe Redhat has already brought their version of the kernel up to ALSA
1.0.2.  Try changing  KERNEL_VERSION(2, 6, 2) to KERNEL_VERSION(2, 6, 1)
at line 423 in adriver.h.
