So, looks like the culript is ntoh_syserr_conv in src/rx/rx_misc.c,
which explicitly returns ENOSPC instead of EDQUOT when Solaris is
detected. I've attached a patch (untested) to just return EDQUOT when
it's defined, and ENOSPC otherwise. There's a lot of other code in
there, though, that assumes EDQUOT doesn't exist on Solaris at all.
There's plenty of other functions that appear to have the same issue as
this that I didn't touch at all.

It seems like a lot of conditionals could be changed from
defined(AFS_SUN5_ENV) to defined(AFS_SUN5_ENV) &&
!defined(AFS_SUN58_ENV) or something, but I thought checking on
EDQUOT's presence would be more robust.

Thanks.  I will commit a fix.
