Unfortunately, strip just strips off *all* symbol information. The DLL
mechanism is just a fairly crude structure piggybacking off the COFF
symbol table, and it's possible that tools like strip don't know to
leave the import and export tables alone.

ELF versions of strip generally know not to strip off the shared library
interface information, because it usually lies in a different section
with a well-known name. I guess the PE version of strip also needs to be
taught to do this.

For now, your only recourse is downloading the source for cygwin.dll,
and compiling it without a -g flag. It'll still have some symbol
information, but it won't be so large.
