========== Build: 13 succeeded, 0 failed, 0 up-to-date, 0 skipped =========

Okay -- the build succeeded.  And I figured out what happened:

1.  I initially attempted to build WebKit in /cygdrive/d/Development/WebKit.
2.  I had a pre-existing copy of Cygwin installed, and assumed this would be
sufficient to build.
3.  Build failed.
4.  I used the WebKit-team provided tool to download the requisite build tools.
5.  I tried building WebKit again, which failed.
6.  I moved the sources (but not the WebKitBuild directory) to
/cygdrive/c/Fulgham (the Home Directory) and lo-and-behold the build succeeded.

CAUSES:
1.  My original install of Cygwin was missing a few tools, namely gperf.
2.  The missing gperf caused some zero-length files in the DerivedSources tree.
3.  Because the build system does not remove the DerivedSources tree, they
continue to be used from build to build, even after a "build-webkit --clean"
4.  The zero-length files caused the build to fail.

CONCLUSION
* The build system is fine.
* I recommend the "build-webkit --clean" remove the auto-generated files to
save future fellow idiots the time spent tracking this down!  :-)
