Subject: * src/Makefile.in: Don't assume that `ln -f' works.
X-Git-Tag: emacs-24.2.90~584
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=24564fe1aab428c41e053b9c0848d9e7a8f2cb69;p=emacs.git

* src/Makefile.in: Don't assume that `ln -f' works.
Presumably it does work fine on all platforms currently building
Emacs, but the autoconf manual says not to rely on it.
