Module Name:
VcCheck.c
Abstract:
We have found problems with the Visual C++ SP4 and the /O1 flag.
If this tests ask a question you have the wrong version of Visual C++
on your system
This test assumes the tools are being compiled with the same complier
as the Tiano code.
Please see $(EFI_SOURCE)\EFI2.0 Developer's Manual.doc to get the
correct version of Visual C++

Routine Description:
This routine is used to test for compiler isseus with /O1.
If the /O1 compiler option, and C2.dll is got from Visual C++ SP5
(version: 6.00.8168.0), the assember codes after default branch will be
losted. (Execute "cl Visual Ccheck.c /O1 /FAsc" to get detail information)
Arguments:
Value - Test case
Returns:
Test to see if comiler error is present.
