Did I miss it back whenever, or is there really a bug in VAXCRTL that silently
limits the size of a read() to 65535 bytes?  I found this the hard way, while
porting unix "ispell" to vms -- down there in the dirty stuff called by
read(), at _child_open+0b9 there's a "movzwl" that trashes the high half of
the "int nbytes" argument you fed it.  *Why*?!?!  There is no mention of
any limitation in the vax C book [but then again, it's the vax C book].

This is Vax-11 C v2.1 [I should probably have a later one, I know] and the
image header of vaxcrtl contains the string "VAXCRTL ... V04-005" [if that
helps].

I did finally work around the various limitations and have a version of "ispell"
that works under vms, if anyone wants it.
