Yes. > But I expect that many packages will not need this. It shouldn't hurt if they use it. No packages that I know of require C99 and break with C1x. On the contrary, the more typical case is a package that uses C1x features if available. The macro AC_PROG_CC_STDC means "Use the most-recent version of C that's supported", not "Require the most-recent version of C and fail if it's not supported". All gnulib modules (and all packages) should work in such an environment. I'm assuming that C1x will be close to its draft; if it changes, so that C1x is undesirable in important and plausible cases, we'd have to address that. I doubt whether this will be an issue, though.
