Do you have a magic script > somewhere that regenerates config.h.in? It's "autoheader". Whenver you add or remove tests to configure.ac, you need to run "autoconf ; autoheader". If you don't run "autoheader", then even if the autoconf's feature test enables some new feature test, say HAVE_PR_SET_IO_FLUSHER, the feature won't actually be enabled in the #ifdef. Cheers, - Ted
