And, compiling the above with CFront, results in:

c++ -c -depend !Depend -IC: -o @.o.main @.c++.main 
Acorn C++ Language System 3.1 [May 25 1995]
"c++.main", line 5: error:  bool undefined
Command failed with return code 1


Which explains why CFront users won't have seen a problem; they've just
(unwittingly?) used OSLib's definition of bool.

Now, __cplusplus *is* defined by CFront, so using that as a test for
defining bool in types.h is not entirely satisfactory!

Yuk!

OK, it's cool; only a suggestion ;-)
