filename-munging on Solaris. It seems that the sys/stat.h header
file doesn't agree with the stat implementation.
Modified Makefile.gs to properly write the new executable over
the old resource fork for udl. The resource fork originates with
the file udl.r.
Added suggested defines to the README for various Unix platforms.
Man page changes, including grammar and the deletion of a bug that
no longer exists.
Fixed bug where invoking 'udl -u directory' would attempt to
deref a NULL pointer, causing either memory tromping (IIgs) or
a core dump (Unix).
Tested under SunOS 4.x, SunOS 5.x (Solaris), and AIX.
Changed EXTERN to extern in common.h, and added globals.c to compensate.
Fixed bug in IIgs version where invoking "udl -<flags> filename/" (with
the trailing '/') would cause udl to fail due to bad filenames.
Added "help" subdirectory. The file "help/udl" is created at build time,
and therefore not checked in.
Added some "#pragma noroot"s.
The temp file is now created in the same directory as the original file,
then renamed after the conversion is done.
Some small doc changes were made as well, mostly typos and addresses.
