If he's attempting to use a bare MS VC++/C# toolchain he should also
have <errno.h> in his include path under most circumstances, or be able
to enable it with minimum difficulty. He may need to turn on "Extern
C" (Extern C++?) functionality in his project settings to make his
compiler/linker search the include path for non-C# headers however. I
don't recall what they called that setting in the dialogs, but it
shouldn't be too hard to find.
