rpm-4.0.3 has `config.h.in' that can't be automatically recreated from configure.in & acconfig.h, because acconfig.h is missing "templates" for two things that occur in the existing config.h.in -- HAVE_GETMNTENT and fnmatch. I emailed Jeff about the fnmatch thing on 2001 Jul 31, and it was explained that it was essentially cruft. The HAVE_GETMNTENT is easily fixed with a patch to acconfig.h. I'll be attaching a patch or two to fix this.
Created attachment 40788 [details] add HAVE_GETMNTENT template to acconfig.h
Created attachment 40789 [details] comment out fnmatch in configure.in -- it's not used/needed
Fixed in CVS, should be in rpm-4.0.4-0.4 and later.
