Such use inside AC_PATH_PROGS() leads to an obscure error message and does not terminate the configure run if hit (just try configuring without installing the Apache development packages first). Also its message needs quoting otherwise textual commas are considered macro argument separators.

You can fetch the tip of https://salsa.debian.org/shib-team/shibboleth-sp2/-/tree/quoting ( https://salsa.debian.org/shib-team/shibboleth-sp2/-/tree/quoting ) for a possible fix.
