Pb with pro*C / Oracle 11 / VS2010 on Windows server 2008

Question

Hello,
I am migrating an application from Windows server 2003 / Oracle 10gr2 / Visual Studio 2003 to Windows Server 2008 / Oracle 11gr2 / Visual Studio 2010 and I am having some issue with the compilation of our oci files.
After fixing the common issue related to path change for Visual Studio, I ran in the following error message while trying to compile one of my file:
Syntax error at line 48, column 9, file C:\Program Files\Microsoft Visual Studio 10.0\VC\include\vadefs.h:
Error at line 48, column 9 in file C:\Program Files\Microsoft Visual Studio 10.0\VC\include\vadefs.h
typedef W64 unsigned int uintptrt;

PCC-F-02102, Fatal error while doing C preprocessing
Searching on the web lead me first to use a work around to define W64 and _W64, but that only leads to more errors of the same kind after.
Also, I've found that "Error at line 0, column 0" may be an indication of missing semi-column or brace, but as the source file has not been changed during this migration, it is still syntactically correct as it was compiling with earlier version of pro*c. Of course, I have double checked and I don't think I am missing any obvious brace or semi-column, or coma ...
Any help or suggestion will be greatly appreciated.
Thanks
Eric

I'm not sure how much help my post will be, but perhaps it will have some value for you.
There's an unpublished bug on this issue (Bug 10017848 - PRO*C PRECOMPILER CANNOT HANDLE _W64 IN TYPEDEF) but it has not been resolved as of this writing.
If you are not familiar with the purpose of "__w64" (which has been deprecated) you can see the following in the MS documentation:
[url http://msdn.microsoft.com/en-US/library/s04b5w00(v=vs.100).aspx]Visual Studio 2010 __w64 description
Now, one thing that you may be able to use in your situation is to simply make "__w64" an "empty define" at the top of your source file(s) like so:
#ifdef WIN32
#define __w64
#endif
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
#include <sqlca.h>
#include <sqlda.h>
#include <sqlcpr.h>
... rest of code ...Of course the above assumes that WIN32 has been defined - if it has not, you will need to use another symbol, make adjustments, etc.
As an example:
proc define=(_WSTDIO_DEFINED,WIN32) code=ansi_c parse=full common_parser=yes atest.pcIf you have a large amount of files that can be tedious of course but it may be a potential workaround for you.
