Indeed. Gee, this has been broken in 2.59 already!
Before I start digging when this broke, and who else this might need
(I do know that some packages like GCC have specific requirements in
this area): do you need these two lines to work?
Autoconf should have a test to expose this issue, if it still exists
with some make implementations. Also a test to ensure $extrasub works
as expected.

Well, the extrasub likely has a similar issue (which, if its value
contains "$", is likely going to have worse effect on the outcome).
Thanks,
