Allen:

1. Please don't multipost or repeat messages to the same newsgroup.
microsoft.public.dotnet.languages.vc is the best group for managed vc
questions.

2. What does "build but not compile mean"?

3. Several people have answered your question (in different places).
"March" does not point to anything.
