Thank you, Don.  If there's a complete list of platforms for which
ANSI builds are expected to work for 2.6.9, and if possible one for
2.6.8 as well, I'd be interested.  In particular, it would be nice to
know whether 2.6.9 ANSI builds on Linux are expected to work.

Thanks --

   Hi Matt,

   Right now, both 2.6.8 builds both CLtL1 and ANSI on my Ubuntu 12.10
   and WinXP, WinVista and Win7.

   2.6.9 builds CLtL1 and ANSI on WinXP, but not yet on WinVista or Win7.

   Best,

   _don
