[groff] 01/01: hdtbl: A missing prerequisite could cause parallel builds to fail.

[Ingo Schwarze]

schwarze pushed a commit to branch master
in repository groff.

commit 9da689056c8744b11cd8f6ebe5169c036063686c
Author: Ingo Schwarze <address@hidden>
Date:   Wed Dec 26 02:09:38 2018 +0100

    hdtbl: A missing prerequisite could cause parallel builds to fail.
    
    * hdtbl.am (HDTBLPROCESSEDEXAMPLEFILES): requires eqn because
    the .roff.ps target runs HDTBLGROFF = GROFFBIN ... HDTBL_PFLAG =
    groff ... -t -p -e -U  which includes -e.
    This was probably broken since the automake migration in 2014.
    
    Issue found by Stuart Henderson <sthen at OpenBSD>.
