Subject: cleanup: simplify subroutine '&saw_extension'
X-Git-Tag: v1.12b~127
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=995e5ff0da20c9b500ecdd2eee2f793b6a27e980;p=thirdparty%2Fautomake.git

cleanup: simplify subroutine '&saw_extension'

* automake.in (saw_extension): Now that we use the '%extension_seen'
hash only as a set (it's keys being its elements), we can simplify
the implementation of this function accordingly.
