Subject: Unbreak building Emacs on FreeBSD
X-Git-Tag: emacs-26.1-rc1~344
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=c6c05e2aa9d28a74df0b61b4f56745f1248a779e;p=emacs.git

Unbreak building Emacs on FreeBSD

* lisp/emacs-lisp/bytecomp.el (byte-compile-file): Don't create
the temporary file under temporary-file-directory if the file
being compiled is specified by an absolute file name.  This avoids
problems with ACL copying from temporary-file-directory on
FreeBSD.  For the details, see
http://lists.gnu.org/archive/html/emacs-devel/2018-01/msg00513.html.
