That causes cascades of type issues eventaually causing compile errors. EGREP_TRADITIONAL does look to be set earlier in the configure script but is probably getting unset again. It may be related to: https://git.savannah.gnu.org/cgit/autoconf.git/commit/?id=34427e07bc9a619704816f4c333a225d9a28da15 I'm out my depth at this point. Cheers, Richard
