My "Annotated C++ Reference Manual" is packed, and surprisingly in
Stroustrup's Third Edition, there is no mention of the issue in the
entire 1,000 pages. But Microsoft to the rescue:
If you want a backslash character to appear within a string,
you must type two backslashes (\\)
The question of what any specific C++ does if you ignore the warning
is irrelevant, as such behavior in C++ is almost *always* undefined.
Hence the warning.
