BUG: Problems w/ ODBC 32-bit Thunking Installer DLL in Win32s

MORE INFORMATION

To reproduce this problem:

Build the following program to create a 32-bit EXE file (Add ODBC32.LIB and ODBCCP32.LIB to the link libraries in projectsettings):

#include <windows.h>
#include <sql.h>
#include <sqlext.h>
#include <odbcinst.h>

int WINAPI WinMain(HINSTANCE hinst,HINSTANCE pinst,LPSTR szCmd,int nShow)
{
   if (SQLConfigDataSource(NULL,ODBC_ADD_DSN,
      "SQL Server","DSN=Oof\0Server=Oof\0\0"))
   {
      MessageBox(NULL,"SQLConfigDataSource succeeded",
         "SQLConfigDataSource",MB_OK);
   }
   else
   {
      MessageBox(NULL,"SQLConfigDataSource failed",
         "SQLConfigDataSource",MB_OK);
   }
   return 0;
}
				

Install the Win32s subsystem from the Win32 SDK on a WFW 3.11 computer. Run the program on Win32s with the ODBC 2.10a or 2.10b components (these ship with VC++ 2.1,2.2, and 4.0). It will fail to load with a message that a DLL could not load or something similar (depends on the version of Win32s).
