Not really.  It was a developer decision -- not just Chris' alone.  Long 
ago it was determined that the "//x" notation was causing big problems; 
in addition to preventing access to external SMB hosts named with single 
letters, IIRC there were network latencies introduced into what should 
be a local operation.  Search the archives from about 1 year ago for 
"why is 'ls' so slow".

So, the '//x' notation has been deprecated for quite a long time. 
Deprecated means "will be going away soon.  Begin transitioning away 
from this usage or you'll be sorry later."

It's now "later".

Ummm...you didn't show your link command.  Are you using -lcygipc ? 
-L/usr/local/lib ?
