I would expect it is.  The BSD world changed the ttype of size_t, off_t
to 64 bits a really long time ago and in the particular case of NetBSD
versioned the syscalls for binary compat (probably others did too).  I
have viewed "large file support" as a linux and solaris thing only.

This is probably a bigger rototill than anyone has appetite for, but I
wonder if there should basically be a configure test to look for foo64
(by the equivalent of AC_TRY_COMPILE) and if so use it,a nd if not just
use the normal system calls.
