Actually it is defined in libc5 but it's just "struct timespec;" :)
I looked on a glibc box and noticed there are quite a few more lines with
timespec in them than there are in my time.h.

Really I wish I knew C and C++ so Ihad a better grasp on what goes on
between those things. I tried to change the coda.h the was you have it up
there in the dist include file and remake the whole thing but then you get
a error about it being redefined, probably since it is defined in time.h,
just not the same way it is in glibc.

Really we should be close to the end though. This error is fairly close
to the end of the compile from what I see of the directory structure,
although I've been known to be wrong at times.
