[Emacs-diffs] master 6fa8d3c: Let plain ‘make’ work even not GNU Make

[Paul Eggert]

branch: master
commit 6fa8d3c894062e7d3bde2d1ed35b40f2272e59f5
Author: Paul Eggert <address@hidden>
Commit: Paul Eggert <address@hidden>

    Let plain ‘make’ work even not GNU Make
    
    * Makefile.in (top_distclean): Clean makefile as well as Makefile.
    * configure.ac: If not using plain ‘make’, create a makefile
    so that plain ‘make’ simply calls $(MAKE).
