[Insight-developers] VTK_USE_ANSI_STDLIB confusion

[Bill Hoffman]

There must be one hiding in a header file.   The way to find
it is to get the command line for the compiler (cl) that
is being used.   You should be able to find it by showing
the properties of the library or executable with the problem.
Then cut and paste the project options to an editor.
Then add cl /E (restof options) > file.cpp.
This will create a preprocessed file.   Then look at file.cpp
in an editor and figure out which file is including io.h.
