48. m4_require: nested (m4sugar.at:527): FAILED

[Stefano Lattarini]

Hello autoconfers.

When doing a "make check" from the autoconf master branch
(v2.68-95-ge0cb97a), the mentioned test fails, with this log:

  $ cat tests/testsuite.dir/048/testsuite.log 
  #                             -*- compilation -*-

This seems like a spurious error, so I guess you won't need more details; but
if you do, just let me know!
