Hi Paul,

Note that I did rework some things to allow it to work with implicit rules
(previously it only worked for explicit rules) although it still can't be
used as a pattern-specific variable: that will require more effort.  Also
some changes were made to make things a bit more efficient.

many thanks for adding this into the release candidate . Again, I very much appreciate your dedicated work, and even more so after looking at the extra work that was still needed on your side to make the patch acceptable for inclusion into GNU make.

By the way, I stumbled into a minor issue entirely unrelated to the feature above that you may want to fix: The gnulib git repository referenced in bootstrap seems to have changed its location, so you may want it to change it accordingly:

$ git diff bootstrap
diff --git a/bootstrap b/bootstrap
index 05808ee..8f52cc1 100755
--- a/bootstrap
+++ b/bootstrap

   cat <<EOF

Furthermore, as running ./bootstrap adds the gnulib directory, it may be appropriate to add it to .gitignore:

$ git diff .gitignore
diff --git a/.gitignore b/.gitignore
index df60c2c..f03287e 100644
--- a/.gitignore
+++ b/.gitignore

And finally, running ./bootstrap also changes lib/.gitignore and m4/.gitignore, so you may want to consider to commit these changed versions:

$ git diff lib/.gitignore m4/.gitignore
diff --git a/lib/.gitignore b/lib/.gitignore
