Details:

For platforms which don't have the Posix pathconf, maxfilename.cpp should try
harder, and look at (the ANSI-standard) FILENAME_MAX in addition to the other
varieties.  Right now, it decides that NAME_MAX is 14 on MS-Windows, which of
course makes no sense.  One adverse effect of this is that temporary file
names don't get the "groff" prefix, for no good reason.
