[anonymous]

Follow-up Comment #4, sr #110687 (project autoconf):

> Can we see the config.log for -std=c11 only, please?

Should be attached. Invocation was:

autoheader && autoconf && rm -Rf config.status autom4te.cache/ && ./configure
--host=aarch64-linux-gnu CFLAGS="-std=c11"
checking for aarch64-linux-gnu-gcc... aarch64-linux-gnu-gcc
checking whether the C compiler works... yes
checking for C compiler default output file name... a.out
checking for suffix of executables... 
checking whether we are cross compiling... yes
checking for suffix of object files... o
checking whether the compiler supports GNU C... yes
checking whether aarch64-linux-gnu-gcc accepts -g... yes
checking for aarch64-linux-gnu-gcc option to enable C11 features... none
needed
checking for stdio.h... yes
checking for stdlib.h... yes
checking for string.h... yes
checking for inttypes.h... yes
checking for stdint.h... yes
checking for strings.h... yes
checking for sys/stat.h... yes
checking for sys/types.h... yes
checking for unistd.h... yes
checking whether byte ordering is bigendian... no
configure: creating ./config.status
config.status: creating issue618config.h
config.status: issue618config.h is unchanged
