Ah, OK. MAXBLK was increased in OpenBSD:
Revision 1.8, Sun Apr 6 06:11:14 1997 UTC (5 years, 6 months ago)
CVS Tags: OPENBSD_2_1_BASE, OPENBSD_2_1
Changes since 1.7: +4 -3 lines
Allow creation of archives with block sizes up to 64512 bytes
but complain about non-portability if > 32256 bytes.

I didn't bother offering that change to you though :-)
BTW, I finally read far enough down on the SunOS 'tar' manual page to
This variable is used to override the default behavior
of tar, provide compatibility with INTERACTIVE UNIX
Systems and SCO UNIX installation scripts, and should
not be used in new scripts. (It is intended for compa-
tibility purposes only.) When set, the following
options behave differently:
Uses filename to obtain a list of command line
switches and files on which to operate.
-e Prevents files from being split across volumes.
If there is insufficient room on one volume, tar
prompts for a new volume. If the file will not
fix on the new volume, tar exits with an error.
I don't imagine NetBSD needs that much Solaris compatability, but it
does explain how they deal with the '-F' conflict.
