dependency tracking error message

[Karl Berry]

Looking at the automake-patches that have accumulated, I saw one to
improve the error message if dependency tracking fails. Copied below.

It seems generally sensible to me, though I would change the wording a
little, and there is a spurious "the", so, revising the proposed text:

  AC_MSG_FAILURE([Something went wrong bootstrapping makefile fragments
  for automatic dependency tracking.  If GNU make was not used, consider
  re-running the configure script with MAKE="gmake" (or whatever is
  necessary).  You can also try re-running configure with the
  '--disable-dependency-tracking' option to at least be able to build
  the package (albeit without support for automatic dependency tracking).])

Confirm/deny? Further suggestions? --thanks, karl.

Subject: [PATCH] Improve the error message when the dependency tracking fails

The dependency tracking may fail with a non-intuitive error
that "Something went wrong ..." if the package expects
GNU make to process its Makefile.am files and other make
implementation is used by default (e.g., Solaris make).
This patch adds a hint to the error message that the user
may try to specify GNU make command as a configure argument.
