[Bug-tar] [PATCH] tests: avoid test failure with non-ancient autoconf

[Jim Meyering]

Hi Sergey,

Here's a patch I found useful.
There's probably a way to make AS_ECHO_N work in this context,
but IMHO, the obfuscation is not worth the nominal portability,
since this type of trivial printf use has worked everywhere
for a decade or so.

Thanks,
Jim

Subject: [PATCH] tests: avoid test failure with non-ancient autoconf

Running "make check" would fail with this:
  T-nonl.at:30: error: m4_divert_push: cannot change diversion
  to `GROW' inside m4_expand
* tests/T-nonl.at: Use printf in place of AS_ECHO_N.
These days, printf should work for everyone.
