$ bin/automake --help
Unrecognized escape \K passed through at bin/automake line 8135.

Here's line 8135:

      $output =~ s/^((#.*)?\n)*\K/.POSIX:\n\n/;

Solaris 10 'perl --version' says it's Perl v5.8.4. v5.8.4 is dated 2004 
but \K was added in v5.10, according to:

https://metacpan.org/release/RGARCIA/perl-5.10.0/view/pod/perl5100delta.pod#K-escape

'configure' says perl v5.6 is required and v5.10 is recommended, so 
v5.8.4 should work even if not recommended. v5.6 came out in 2000, 
v5.8.4 in 2004, v5.10 in 2007; Solaris 10 is dated 2005 and Oracle 
currently plans to support it through January 2027 
<https://blogs.oracle.com/solaris/post/new-end-date-of-extended-support-for-oracle-solaris-10-and-113>.

A simple fix would be for Automake to require Perl 5.10; this'd mean I'd 
have to build Perl to test Automake on Solaris 10.

I was using the release tarball.
