Probably due to the recent Bison 3.3 release, app-crypt/mit-krb5-1.16.3 doesn't compile anymore. The error is the following: bison -y /var/tmp/portage/app-crypt/mit-krb5-1.16.3/work/krb5-1.16.3/src/kadmin/cli/getdate.y /var/tmp/portage/app-crypt/mit-krb5-1.16.3/work/krb5-1.16.3/src/kadmin/cli/getdate.y:180.1-7: error: POSIX Yacc does not support %expect [-Werror=yacc] %expect 4 ^~~~~~~ When invoking bison without -y, the file is processed okay.
Adding -Wno-yacc to bison -y fixes it for me (MakeFile in kadmin and kadmin/cli), without -y the file is not generated in my case.
(Without -y the file is called getdate.tab.c instead of y.tab.c, so it needs to be moved/copied. -Wno-yacc seem to be better solution.)
GNU Bison NEWS * Noteworthy changes in release 3.3.1 (2019-01-27) [stable] ** Changes The option -y/--yacc used to imply -Werror=yacc, which turns uses of Bison extensions into errors. It now makes them simple warnings (-Wyacc). commit 5be2c1812c5d672bb3d2f3ea8ba25f260abbf45f Author: Lars Wendler <polynomial-c@gentoo.org> Date: Mon Jan 28 01:46:04 2019 +0100 sys-devel/bison: Bump to version 3.3.1. Removed old. Package-Manager: Portage-2.3.58, Repoman-2.3.12 Signed-off-by: Lars Wendler <polynomial-c@gentoo.org>
