implemented as macros now so that the code is embedded in the mainline
and allowing compiler optimisations.

For instance, character conversions functions such as toupper, tolower,
isalpha, isnum etc are now implemented as macros, not functions.


I had heard at one point, but not sure, that some C compilers would
process "printf" internally instead of calling an external routine. But
am not sure of that. (remember that in some environments, the compiler
and linker are the same thing).
