"touch gram.c" then "make" will build again the affected files. Which is different from "rm gram.c"... A "touch gram.y" will trigger a rebuild of "gram.c" (and "gram.o"). Maybe Makefile has an option to be a little bit more conservative and rebuild any removed intermediate file even if not required. > > What was the consensus when Peter did the change ? > > It was an experiment, nothing more; or at least that's how I saw it. ok. -- Cédric Villemain +33 (0)6 20 30 22 52 http://2ndQuadrant.fr/ PostgreSQL: Support 24x7 - Développement, Expertise et Formation
