on my sparc system, things built fine after i added the nanosleep prototype. i dont know if the "struct regs" problem Frederik is seeing is due to the C compiler barfing on earlier errors (since things like to snowball), or some other problem. i know that running on a sparc64 kernel with a sparc32 userland results in lots of errors if the --host isnt forced to match the userland (config.guess returns a sparc64 host). i dont have any systems running a sparc32 kernel or a sparc64 userland, so i cant really test those setups. sparc32 user on a sparc64 kernel is by far the most common combo at any rate ... -mike
