I believe a solution was suggested before: distribute a .bat file for
common symlinks.  If the awk package contained /bin/awk.bat (which called
gawk.exe), "awk" would work in both the cmd prompt and Cygwin shells.
Similarly for "vi", "gunzip", "[ef]grep", "[ck]sh", "zcat", etc.  One
problem is that parameter passing is tricky, and may need advanced cmd.exe
features (i.e., won't work on Win9x)...  Another is that you can't use
commands like "exit" in those batch files (or you'd need to "call" them,
which breaks the transparency).

A question to the OP: which scripts?  If they are shell scripts, you
shouldn't have this problem in the first place.  Are you using "awk" in
batch files?

Oh?  Then what's with the @pathnames
(<http://cygwin.com/cygwin-ug-net/using-specialnames.html#AEN830>)? ;-)
