Is it likely that that some packages won't want -std=gnu++11, but other packages will?

That's what we do on the C side, anyway: AC_PROG_CC_STDC tries to get a "reasonable" set of features, and feature-test macros are available for each feature of interest. _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx https://lists.gnu.org/mailman/listinfo/autoconf
