Is it OK to upgrade autoconf\config.guess?

Tue Jul 14 00:03:45 PDT 2015

SVN version is from 2011 and does not support MSYS2.

Current version from GNU does support MSYS2.

http://git.savannah.gnu.org/gitweb/?p=config.git;a=blob_plain;f=config.guess;hb=HEAD

Is it OK to replace just this file with the new config.guess ?
