Thanks for reporting this.
I suspect that this is an upstream bug in makedepend, in that it does 
some canonicalization on paths, and assumes that '//' is the same as '/' 
everywhere in a path, which isn't true for an initial '//' (but happens 
to work on Linux, etc.)

See SUSv4 Base specifications, section 4.13 "Pathname Resolution" ([1], 
registration required):

"If a pathname begins with two successive <slash> characters, the first 
component following the leading <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."

Unfortunately, you're probably going to have to fix this yourself, if 
it's causing you problems.

Fortunately, makedepend is relatively small (See [2]).
