[Emacs-diffs] emacs-26 c6c05e2: Unbreak building Emacs on FreeBSD

[Eli Zaretskii]

branch: emacs-26
commit c6c05e2aa9d28a74df0b61b4f56745f1248a779e
Author: Eli Zaretskii <address@hidden>
Commit: Eli Zaretskii <address@hidden>

    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.
