Not as much silly as misguided.  The mapping from long filenames to short
filenames happens at the Windows level -- there is no way for a program to
predict what short name a particular long name will map to.  Thus, there
is no way to track the short names back to the long names, sorry.

One wild idea: you could try matching the MD5 sums of the bz2 files to the
contents of setup.ini...  Given that the short names do share the first 6
characters with the long names, this shouldn't be too time-consuming.
But, as Larry said already, <http://cygwin.com/acronyms/#SHTDI>, and it
probably won't be anyone but you.
