Silly compiler switches

[JD]

Hi folks,
I am developing a COM-ATL application with VS2003.NET, and I run into this
situation:

I have built the app to a satisfactory point and after that I start playing
with compiler optimization switches.

I would like to go back to initial switch settings.

I kept the initial bins version .exe & stuff of the program. Below is a
comparison (disassembly) example of the original version and the actual
version:

Any ideas what will be the compiler switches to get to the initial bin
generated?

C++ constructor _initterm( __xc_a, __xc_z ) for CComModule _Module;

Initial:

push esi

mov esi,offset _Module

mov ecx,esi

call ATL::CAtlModule::CAtlModule

push offset $E6

mov dword ptr [_Module],offset ATL::CComModule::`vftable'

mov dword ptr [ATL::_pModule],esi

call _atexit

pop ecx

pop esi

ret

Actual:

mov ecx,offset _Module

call ATL::CComModule::CComModule

push offset $E6

call atexit

pop ecx

ret

ATL::CComModule::CComModule:

push esi

mov esi,ecx

call ATL::CAtlModule::CAtlModule

mov dword ptr [esi],offset ATL::CComModule::`vftable'

mov dword ptr [ATL::_pModule],esi

mov eax,esi

pop esi

ret

Actual Compiler switches are:

/Og /Ob2 /Oi /Os /Oy /D "WIN32" /D "NDEBUG" /D "_WINDOWS" /GF /FD /EHsc /MD
/GS

/Yu"stdafx.h" /Fp"Release/MyApp.pch" /Fo"Release/" /Fd"Release/vc70.pdb" /W3
/nologo /c /Zi /TP

Thanks
