This suggests that the result of abs is signed and need an explicit
conversion to unsigned.
I'm not sure that this is beneficial.
OTHO what is abs anyway ?
Is it some kind of builtin overloaded function that

Typecast is not only inlined but even builtin (in C source code it not
even looks like a function; this is PASCAL specific stuff.)
abs() is a special beast, anyway...

for different argument types ?
BTW.: Funny stuff:
Is the argument of abs() would be fixed to signed, and we would have
automatic type conversion

Correct. There is no abs() for unsigned types.

One can always use explicit type conversions. MSElang principle is to make

Why? What about Delphi
cardinalvar:= $;
integervar:= abs(cardinalvar);
?
BTW, Free Pascal has no unsigned abs().

There is no abs() for unsigned - one can not do doing_smth(unsigned) with
abs().

A type cast, CPU wise, is a no-op, quite simply.
Correct, if the sizes of the types are the same a type conversion says to the
compiler I know what I do.
