[Insight-developers] atoll and strtoll issues for VC express

[Luis Ibanez]

Hi Wanlin,

I haven't been able to find a clear answer about the
use of "atoll" on Windows.

So,
using using #ifdef seems to be a reasonable first approach.

Just be weary that WIN32 is not only defined in Visual Studio,
but also in Cygwin and MinGW, so the set of #ifdef may be a
bit more complex.


See for example, line 524 of

                  ITK/Code/Common/itkMacro.h

 #if defined( _WIN32 ) && !defined( __MINGW32__ ) && !defined( __CYGWIN__ )
