Honestly, there is no "right thing" here.  As you know, currently on 
cygwin IPC services are provided by the cygipc package (-lcygipc) which 
has only recently been added to the official distribution -- although 
the library has been around for years.

Long term, we'd like to complete the cygwin server, which will be an 
intrinsic part of the cygwin kernel, and not an add on package.  So I 
hesitate to suggest "use -lcygipc" or recommend that upstream packages 
be modified to suit cygipc...because hopefully, eventually, cygipc will 
go away and the native kernel (+cygserver) will handle all of this.

So, I'd say just do what works (symlinks?  fine...) and wait for "the 
real IPC server" to come along.

Or help make cygserver a reality sooner.
