--- Comment #3 from cqwrteur <unlvsur at live dot com> --- Created attachment 50575 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=50575&action=edit The log file shows it does check stdio.h conftest.c:10:10: fatal error: stdio.h: No such file or directory 10 | #include <stdio.h> This is just incorrect tbh.
