Mostly.  CAlive extends a few things syntax-wise, but on the whole,
everything that I know how to program in C/C++ code will compile with
zero changes in CAlive, and it will function identically.

CAlive extends many things:
    https://github.com/RickCHodgin/libsf/blob/master/books/rdc/rdc.odt

But, it will also work as a standard C compiler on most everything.

CAlive will upsize signed and unsigned values to the next largest size
fundamental type in order to compare them.  To keep them the same size,
they must be cast one to other's type.

If no larger fundamental type exists, then it will be upsized to a "bi"
type, which is a fundamental type in CAlive, which is an arbitrary size
"big integer" of the next largest size, such as 64-bit to 128-bit).
