AX_CXX_COMPILE_STDCXX_11 doesn't work: syntax error near unexpected token `,'

Trying to use AX_CXX_COMPILE_STDCXX_11 in my configure.ac file like this:

...
AX_CXX_COMPILE_STDCXX_11(, optional)
...

However, results in error:

./configure: line 16126: syntax error near unexpected token `,'
./configure: line 16126: `AX_CXX_COMPILE_STDCXX_11(, optional)'

I've also placed this file into m4 directory next to configure.ac file and have AC_CONFIG_MACRO_DIR([m4]) called in configure.ac in the very beginning. Did anyone faced anything like that before?

Installing autoconf-archive via brew fixed this on macOS 13.6.6 for me when I ran into this building "libxls".

% brew install autoconf-archive

Adding ACLOCAL_AMFLAGS = ${ACLOCAL_FLAGS} -I m4 to the top-level Makefile.am helped to resolve this issue for me.
