Yufeng,
I've recently brought the "prestruct-c"
compiler back to "life"
Great archeology! It seems you've unearthed a snapshot from the brief
period when Dennis was struggling to reconcile byte addressing with BCPL
pointers--the seminal innovation of C. In characteristic Unix fashion, he
was trying out his ideas as they developed.
I had forgotten that product types were under con-struct-ion at the same
time. That really was a big bang.
