This did it, Neil!  I unchecked the daylight savings box and reinstalled 
Lilypond after wiping out the old cache (not sure if these steps were 
necessary but I wanted to start out fresh), and after the first run, the 
cache was NOT rebuilt again.  The difference in speed between Vista and 
Ubuntu compiling a lilypond file is now negligible, measured in 
fractions of a second instead of minutes. Perhaps this tip should be 
posted somewhere official, as a warning on the download page for 
installing on Vista or maybe on Valentin's FAQ page?  It's beyond my 
abilities to figure out how to keep this from happening, but for now at 
least it's an easy workaround.

What I have not tried is re-checking the automatic daylight-savings 
adjustment box to see if it reverts to the old behavior of always 
rebuilding the fontconfig cache.  If you'd like me to do this for the 
sake of testing, I will.

Glad to put this one to rest :)

Jon
