Subject: [ng] dist: fixup: run slower compressors first
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a91c15c3a71d8bfa0398a0dfcab570f66a9a846a;p=thirdparty%2Fautomake.git

[ng] dist: fixup: run slower compressors first

For better parallelism in "make dist".  This was already the case
for mainline Automake, but our recent changes to the dist-related
code in Automake-NG had broken that invariant.

* automake.in (handle_dist): Here, use 'unshift' rather than
'push' on '@archive_formats'.
