This was probably "/ZI".

"/ZI" means "symbolic information for edit-and-continue" and is only VC6.
"/Zi" means "symbolic information", and is in _all_ VC versions.

/ZI doesnt give us much for Python.  Im my experience, changing Pythion
binaries while debugging is cute, but pretty useless as often a .py file
_also_ needs changing, and Python doesnt really support "edit-and-continue"
in the same way.

MSVC kindly bumps a "/Zi" option to "/ZI" automatically and silently when
doing the VC5->VC6 updgrade

So I can see no reason not to use "/Zi" for both.  From the GUI, it should
be obvious - its the symbolic debug option without edit-and-continue.

Mark.
