For no good reason, I've been wondering about the
early history of C
compilers that were not derived from Ritchie, Johnson, and Snyder at Bell.
Especially for x86. Anyone have tales?
Were any of those compilers ever used to port UNIX?
As a slightly separate addendum, I'm curious about the slightly later
history of compilers for commercial UNIX distributions. Were these derived
from the Bell/BSD sources or were they "clean room" approaches? I'm
thinking of SunPRO, IBM XL C, the MIPS compiler, DEC GEM, etc.
