But the 4000-character limit is documented by Autoconf to be a limit
on the length of lines of sed's input data, not a limit on the total
size of the sed script.
However, it turns out that we check the 99 commands limit incorrectly,
as the sed script in question contains 100 commands. I installed this
patch. It's conceivable that this patch fixes the problem; it'd be
nice to test this.
I found what appear to be some other off-by-one issues that cause
98-line scripts instead of 99, but these are not bugs so I didn't fix
it. Also, that code is too hairy (does anybody understand it other
than its author? I sure don't) so I didn't want to mess with it.
In the long run we're probably better off finding a working 'sed' than
continuing to cater to broken ones.

* lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
that caused config.status to generate 100-command sed scripts; the
portable limit is 99.
