c++ - vs 2008 623 compiler errors

Question

I have a c++ console app that has been doing just fine and upon clean make started throwing compiler errors. Obviously I've redefined or omitted something, but I'm not sure what.

C:Program FilesMicrosoft Visual Studio 9.0VCincludeexcpt.h(60) : error C2065: '_$notnull' : undeclared identifier
C:Program FilesMicrosoft Visual Studio 9.0VCincludeexcpt.h(60) : error C3861: '_Pre1_impl_': identifier not found
C:Program FilesMicrosoft Visual Studio 9.0VCincludeexcpt.h(60) : error C2146: syntax error : missing ')' before identifier '_Deref_pre2_impl_'
C:Program FilesMicrosoft Visual Studio 9.0VCincludeexcpt.h(60) : warning C4229: anachronism used : modifiers on data are ignored
C:Program FilesMicrosoft Visual Studio 9.0VCincludeexcpt.h(64) : error C2059: syntax error : ')'
C:Program FilesMicrosoft Visual Studio 9.0VCincludectype.h(94) : error C2144: syntax error : 'int' should be preceded by ';'
C:Program FilesMicrosoft Visual Studio 9.0VCincludectype.h(94) : error C4430: missing type specifier - int assumed. Note: C++ does not support default-int

I'm sure it's something obvious, but I don't see it. One other thing, I reloaded the project from a backup copy.

Edit:

Using /showIncludes as suggested by Michael Burr gives the following:

Note that there's a circular reference via sourceannotations.h. I see what the problem is, but have no idea how to fix it.

JaredPar's answer has something to do with it, but you shouldn't have to include sal.h yourself - something's causing the wrong sal.h to be picked up (or another wrong header). <sal.h> should be included by <crtdefs.h> which is included by the standard headers, but clearly the right one isn't being picked up for some reason.

Try using the "/showIncludes" option ("Configuration Properties/C/C++/Advanced/Show Includes" in the IDE's project options) to see what headers are being included from where.
