Autoconf fails tests 24 and 26 with M4 branch-1_4 now

[Ralf Wildenhues]

I'm seeing further destabilization in the Autoconf/M4 combo.
My increased focus on testing this combination is because:
- there was an announcement that the next Autoconf release may be
  released soon,
- due to Stepan's recent changes to Autoconf, it practically now
  *requires* at least M4 1.4.7 to operate properly.  So if it finally
  turns out that 1.4.7 has a regression over previous M4 releases, there
  is a trap situation for users.

Here are the failures.  By the way, there was a time when version
requirements were not quite as strict, by the way.

Cheers,
Ralf
