Subject: automake: avoid unnecessary use of \K.
X-Git-Tag: v1.16.90~49
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=95c0aa1825a1d4c1510393a5829552b55ebb7f13;p=thirdparty%2Fautomake.git

automake: avoid unnecessary use of \K.

This fixes (part of) https://bugs.gnu.org/67891
and follows up on https://bugs.gnu.org/55025.

* bin/automake.in (generate_makefile) <posix>: avoid use of
\K when removing comment and blank lines before a .POSIX target,
since Solaris 10 has perl 5.8.4, and \K was added in 5.10.
