CPP) to create platform independent files. Unfortunately, that means that every config.status (or configure) run invariably causes a relink of the postmaster and also that we can't put these files in the distribution (usefully). So we make it a little smarter: when the output files already exist and it notices that it would recreate them in identical form, it doesn't touch them. In order to avoid re-running the make rule all the time we update a timestamp file instead. Update release_prep accordingly. Also make Gen_fmgrtab.sh use the awk that is detected at configure time, not necessarily named `awk' and have it check for exit statuses a little better. In other news... Remove USE_LOCALE from the templates, it was set to `no' everywhere anyway. Also remove YACC and YFLAGS from the templates, configure is smart enough to find bison or yacc itself. Use AC_PROG_YACC for that instead of the hand-crafted code. Do not set YFLAGS to `-d'. The make rules that need this flag should explicitly invoke it. YFLAGS should be a user variable. Update the makefiles to that effect.
