hotspot VS 2010 project build fails looking for precompiled header

[Pete Brunet]

When I try to use jdk7 with an AT (Assistive Technology) I get a crash
so I'm in the process of  building a hotspot I can run as VS 2010
project.  I've gotten to the point of creating a VS 2010 project.  When
I start the VS 2010 build I get the following error.  Do you have any
ideas on resolving this problem?  Thanks, Pete
