I'm using #ifdef MSVC to set MAX_SPLITS to a different value on Windows
MSVC.

I'm currently working on making my samples run cleanly without warnings on
Windows.  fopen gives warnings in MSVC (see below), and I've run into file
I/O errors on Windows (which do not occur on Linux).  Here are some Windows
compile warnings with fopen:

samples\alreadysorted.cpp(34) : warning C4996: 'fopen': This function or
variable may be unsafe. Consider using fopen_s instead. To disable
deprecation, use _CRT_SECURE_NO_WARNINGS. See online help for details.
        C:\Program Files (x86)\Microsoft Visual Studio
8\VC\INCLUDE\stdio.h(234) : see declaration of 'fopen'
samples\alreadysorted.cpp(65) : warning C4996: 'fopen': This function or
variable may be unsafe. Consider using fopen_s instead. To disable
deprecation, use _CRT_SECURE_NO_WARNINGS. See online help for details.
        C:\Program Files (x86)\Microsoft Visual Studio
8\VC\INCLUDE\stdio.h(234) : see declaration of 'fopen'
samples\alreadysorted.cpp(67) : warning C4996: 'fopen': This function or
variable may be unsafe. Consider using fopen_s instead. To disable
deprecation, use _CRT_SECURE_NO_WARNINGS. See online help for details.
        C:\Program Files (x86)\Microsoft Visual Studio
8\VC\INCLUDE\stdio.h(234) : see declaration of 'fopen'

What is the best platform-independent file I/O approach to use for writing
and reading bytes?  ofstream writes 4031 bytes when I tell it to write 4000
on Windows, so that doesn't seem appropriate.
