Given the changes in key_t's definition as of cygwin-1.3.11, I've 
relased a new version of cygipc, with some major changes.

Because of the key_t change, one can no longer compile IPC programs if 
both cygipc-1.11 or older is installed, AND cygwin-1.3.11 or newer is 
installed -- they are incompatible.  (However, programs that were 
PREVIOUSLY compiled, against cygwin-1.3.10 or older and the old cygipc's 
will continue to work properly even with new cygwin kernels).

The daemon is now called ipc-daemon2.exe, so that it can coexist with 
the older cygipc daemon.  The new daemon uses *different* files in /tmp.

Old programs (that is, previously compiled) will continue to work -- but 
will use ipc-daemon.exe.  Newly compiled programs will use 
ipc-daemon2.exe -- but you must compile with cygwin kernel 1.3.11 or newer.

The point: old programs use ipc-daemon.  new programs use ipc-daemon2. 
Both will RUN under any cygwin kernel (within reason) -- but if you're 
compiling, you must make sure your kernel and cygipc "match" -- old 
kernel, old cygipc; new kernel, new cygipc.
