No, but that has already been discussed and there is no need to repeat it.

No, because C is a typed language.  It is not a particularly strongly 
typed language, and some people write their C code in very weak ways 
(making everything an "int").  But it is a big step up from a typeless 
language and lets the compiler do a good deal of checking.

C has different sized types as part of the language, not just a library.

Very good.  I was commenting here specifically on Forth as found on the 
GA144 toolchain, but I am glad you have namespaces and long identifiers.

Again, the context has been Forth on the GA144 - and that /is/ 
colorForth.  But again, I am glad to hear that it is not the state of 
Forth in general.
