I really appreciate the leads and code you've provided.  Could we please
discuss only on the Cygwin mailing list?  That's the convention we have,
barring extraordinary circumstances :) .  It allows for public review.

Installing gettext-devel and popt-devel got rid of my configure issues.  I
updated lpr/Printer.cc and cygdrop/cygdrop.cc to use strcasecmp() instead of
stricmp() and strcmpi() respectively.  I did not (yet) look into the
compiler warnings that spew during the build of some of the cygutils
executables.

At that point I could reproduce your first mkshortcut issue.  Your patch
seems to fix that issue.  So far, so good.

The second issue with the non-absolute path is more problematic.  Without
your second patch, I do see the issue but only on the 2nd or later
invocation.  In other words, if the xyzzy.lnk file does not initially exist,
the command 'src/mkshortcut/.libs/mkshortcut xyzzy' works and does create
the link file.  Another invocation then shows the error.  Is it simply
mis-reporting that there's an existing link file?  I'm also assuming you're
in the /usr/src/cygutils-1.4.14-1.<arch>/build directory when you issue that
command.
