machines with oddball char * formats

[Daryl Clevenger]

Although I don't know the details, from what I have heard the DEC-20 suffers
from a similar problem.  Wordsize is 36 bits, I think all pointers are 18-bits
and chars can not be packed to have a pointer to them.  Also, you can define
how many bits are in a byte (although this may not necessarily be a char).
There is a version of pcc that I have seen for the 20, but I have never used
it and I hear that it doesn't generate correct code anyhow.
