I swear I reported this earlier, but now I can't find the bug :/ Fortunately, autoheader doesn't appear to be used anywhere important, however, it is still broken by Perl 5.26 '.' removal from @INC ( it falls in the realm of "do" being broken, as per: https://wiki.gentoo.org/wiki/Project:Perl/Dot-In-INC-Removal#The_problem_with_do This is exposed by a test failure that invokes autoheader, where autoheader has the problem code involving a chdiring into a tempdir, and then loading files from it assuming '.' in @INC, causing the test to fail. Of course, as with bug #554748 , this is likely to affect all historical versions of autoconf, and all will need some solution applied ( or removal ) Output from test 038: +++ /var/tmp/portage/sys-devel/autoconf-2.69-r3/work/autoconf-2.69/tests/testsuite.dir/at-groups/38/stderr 2017-07-18 23:08:28.853963234 +0000 @@ -0,0 +1,2 @@ +do " tmp dir with funny ' $x & #! name /ah9v3DXw/traces.pl" failed, '.' is no longer in @INC; did you mean do "./ tmp dir with funny ' $x & #! name /ah9v3DXw/traces.pl"? at /var/tmp/portage/sys-devel/autoconf-2.69-r3/work/autoconf-2.69/bin/autoheader line 186. +autoheader: error: AC_CONFIG_HEADERS not found in file with funny ' $x & #! name .in ./tools.at:1310: exit code was 1, expected 0 38. tools.at:1278: 38. autotools and whitespace in file names (tools.at:1278): FAILED (tools.at:1310)

Created attachment 487898 [details, diff] patch fixing autoheader with Perl 5.26 Please review the attached patch. It makes the test suite pass with Perl 5.26.
commit 565193ae54cfbf09e592ed5607b3775986d93c53 (HEAD -> master, origin/master, origin/HEAD) Author: Lars Wendler <polynomial-c@gentoo.org> Date: Fri Aug 4 17:17:17 2017 sys-devel/autoconf: Revbump to add another perl-5.26 fix (bug #625576). Package-Manager: Portage-2.3.6, Repoman-2.3.3 Keeping this bug open for possible fix of older autoconf versions. I only fixed autoconf-2.69
Just confirming this bug is still occurring in 2.64, which appears to be needed by GCC 8. Really not interested in stabilizing perl 5.26 until this is put to bed.
