Of course, you could live on the edge and NOT apply the security update. I
have the RTM version of Visual Studio and don't have any of these problems.
The way I see it as an individual developer and time is money is that I can
keep up with the MS Security Updates and then have to recompile ALL my
projects and add "special" header files to them to make sure the correct CRT
is found which would take way too much time OR I can NOT install the update
and keep developing the way I have been developing the last few years with
nothing special to be done. I weighed the pros and cons and made my choice.
