Not only is it perfectly compatible with Linux, but it is allowed by
POSIX. This is a design decision that all portable programs must be aware
of - you cannot blindly use '//' to mean '/', and not just because of cygwin.

"A pathname that begins with two successive <slash> characters may be
interpreted in an implementation-defined manner, although more than two
leading <slash> characters shall be treated as a single <slash> character."
