[Emacs-diffs] master 2534676 2/2: Simplify setfattr use by assuming GNU make |
Date: |

branch: master
commit 25346768fac53687c97c213fb99ff18fa805b073
Author: Paul Eggert <address@hidden>
Commit: Paul Eggert <address@hidden>
Simplify setfattr use by assuming GNU make
* Makefile.in (PAXCTL_if_present, SETFATTR_if_present): New macros.
(emacs$(EXEEXT), temacs$(EXEEXT), bootstrap-emacs$(EXEEXT)): Use them.
Simplify by using GNU make rather than shell conditionals,
by using ln -f rather than rm -f followed by ln,
and by preferring $@ to spelling out the destination.
