From: Ben Hutchings Date: Mon, 30 Sep 2013 01:51:23 +0100 Subject: DocBook: Make mandocs parallel-safe Forwarded: http://mid.gmane.org/1380502603.14493.9.camel@deadeye.wl.decadent.org.uk Two concurrent calls to cmd_db2man may attempt to compress manual pages generated by each other. gzip can then fail due to an input file having already been compressed and removed. Move the gzip command to the top-level mandocs target.
