Yes it it. I have the same problem with kde.
A short fix is to encapsulate the ipc header files ipc.h and shm.h with
#ifdef __cplusplus
extern "C" {
#endif
#include <sys/ipc.h>
#include <sys/shm.h>
#ifdef __cplusplus
}
#endif
Currently I'm preparing a patch for the cygipc maintainer to integrating this
into future releases.
