From: "cvs-commit at gcc dot gnu.org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug c/91092] Error on implicit function declarations by default Date: Fri, 01 Dec 2023 07:12:13 +0000 [thread overview] Message-ID: <bug-91092-4-Eu8NrnyEQd@http.gcc.gnu.org/bugzilla/> (raw) In-Reply-To: <bug-91092-4@http.gcc.gnu.org/bugzilla/> https://gcc.gnu.org/bugzilla/show_bug.cgi?id=91092 --- Comment #22 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Florian Weimer <fw@gcc.gnu.org>: https://gcc.gnu.org/g:55e94561e97ed0bce4774aa1c6b5d5d82209a379 commit r14-6033-g55e94561e97ed0bce4774aa1c6b5d5d82209a379 Author: Florian Weimer <fweimer@redhat.com> Date: Fri Dec 1 08:10:13 2023 +0100 c: Turn -Wimplicit-function-declaration into a permerror In the future, it may make sense to avoid cascading errors from the implicit declaration, especially its assumed int return type.
