We have an old programme compiled and linked OK using VC++ 5.0 and would like to compile it using VC++ 6.0. No MFC used, old xvtdsp32 used in that project. When we try to do it we get error: winnt.h(161) : error C2143: syntax error : missing ';' before '*'. Which it is not ( i.e. no ';' is missing). Where and how do we look for the real problem?
