Hi Tom,

Thanks for your quick reply!
I have looked into those system header files, and don't know what they're for because I'm not a C programmer :-(

Following is the Data block descriptor in the stream.h file that declares the projid_t.

Thanks again,
Thanh

Hmm --- the "parse error" suggests that sys/socket.h on your platform
has some inclusion dependency that we are failing to provide for.  Can
you find out what it is?  (Hint: look for "projid_t")
