this is due to a semantic change in c23
https://thephd.dev/c23-is-coming-here-is-what-is-on-the-menu similar
to https://lists.gnu.org/archive/html/bug-texinfo/2024-08/msg00021.html

while troubleshooting this, using autogen on HEAD I get a warning that

configure.ac:776: warning: AM_PROG_MKDIR_P: this macro is deprecated,
and will soon be removed.
configure.ac:776: You should use the Autoconf-provided
'AC_PROG_MKDIR_P' macro instead,
configure.ac:776: and use '$(MKDIR_P)' instead of '$(mkdir_p)'in your
Makefile.am files.
