Note that for any compiler following the implementation advice in the RM
(all currently available Ada 95 compilers do so), the use of the
X'First subscript here is obfuscation. In fact there is no real reason
to suppose that it will work any better than simply saying
C_File'Address, since neither is really guaranteed to work in an absolute
semantic sense, and in practice they are interchangable.
I think it is reasonable to avoid FUD about compilers not doing the
sensible thing if that FUD results in obscuring the code.
