There's nothing wrong with it. In fact I expect that Chris et al. will
change the filename in accordance with the dll naming conventions
painfully hammered out here about 6 months ago.

The issue being that windows doesn't support symlinked .dll's, so the
filename cannot change like it does on unix.

The results were (from memory):
Change the library major version number on ABI changes.
Change the library minor version number on internal changes/header files
changes with the same ABI.
The library name is library<major version>.

So when the cygwin ABI changes in a non backwards compatible way, I
expect that the library will become version 2.x.x, and the filename
cygwin2.dll
