maybe add configure option to compile in the DTD for the XML output.

PROGNAME (with elcerror) doesn't work for aux programs

someone (but probably not me) might make the viewreport example viewer
for the XML output show the file characteristics that are included in
reporting a new file.

increased info for missing files has only been added to human-readable
output.  If someone is using XML misses it, it should be added to the
XML output as well.

include a stdint.h.in file that can replace stdint.h on non C99
conforming systems.  If there's no stdint.h or inttypes.h system
header, copy stdint.h.in to stdint.h and define HAVE_STDINT_H.
The configure script will know type sizes anyway.
