All compilers with properly implemented `const' agree that the types
`const char *const' and `char *' are NOT compatible types. This
means that your response `yes' to the second question suggests that
the `const' qualifiers SHOULD be removed.
Backward compatibility means compatibility with the era when `sys_errlist'
was required (through the lack of `strerror()') which is (approximately)
the era when `const' was not supported.
I would not labour the point but for the fact that this apparent
contradiction between your response to the `Rhetoric' and the remainder
of your email argues that I am still not making myself clear.
