VMS's DEC CC does the same thing as our tool chain. At least on the
VMS 4.4 system I used in college. It got lots of other things
"different" than the unix compilers we were using (pcc derived things
for sun3 and sun4), but this it did the same.
C++ requires exactly one definition, but can have many declarations
(eg only one int foo, but many extern int foo). Actually, conforming
C++ compilers may require exactly one definition. This is listed in
the appendix of one of the Stroustup books as being a departure from
plain old C.
