BF> Can someone comment on the availability of these syscall BF> mappings? ``Syscall'' is another name for ``kernel trap.'' The syscalls for Mach are completely different than the ones for Linux or other unices. The only portability provided by the Hurd is the Posix interfaces defined by the GNU C Library. You should see if MzScheme has been ported to Posix, and if not, suggest that they define a port that uses `read (...)' rather than `syscall (... read ...)'. That's a basic Unix portability guideline: don't use syscalls.
