Subject: Portable syscall inspection

Someone finally noticed that my program that uses ptrace only works on i386..
and, by the looks of it, there is no portable way to refer to the
registers of a
user_regs_struct when inspecting a system call.

I will probably end up making a header file for each architecture that
defines where
in the user_regs_struct things like the syscall number, the return
value and the first 3 parameters are..

has anyone done this already?  or can otherwise save me a lot of time?

Thanks,

Trent
