Follow-up Comment #4, sr #110530 (project autoconf): > Apple had to make this change in order to support Apple Silicon processors No it didn't. At best, Apple just doesn't care much about compatibility with GNU tools.
A simple workaround would be for 'configure' to automatically add -Wno-error=implicit-function-declaration to CFLAGS if it's needed to compile a simple test like "does strlen exist?". Perhaps Autoconf should do that. In the meantime, the advice "configure with CFLAGS=-Wno-error=implicit-function-declaration" will simply have to become de rigueur among people who want to run GNU tools on macOS despite Apple's increasingly-high portability barriers. _______________________________________________________ Reply to this item at: <https://savannah.gnu.org/support/?110530> _______________________________________________ Message sent via Savannah https://savannah.gnu.org/
