Package: src:mozjs60
Followup-For: Bug #905834
User: debian-68k@lists.debian.org
Usertags: m68k
Hello!
I wasn't put in the loop of this bug report, so I was about to
file a new bug report. Luckily, reportbug listed this bug before
I filed a new one. Please always CC debian-$a...@lists.debian.org
in the future.
Anyway, attaching an updated patch for m68k.
Adrian
