If the first parameter of a constructor is marked as unused i always get the error:
x25.cpp:26: error: expected unqualified-id before "const"
x25.cpp:26: error: expected `)' before "const"
x25.cpp:26: error: expected `,' or `;' before "const
where the line is
x25.cpp:26: CommonX25::CommonX25(UNUSED const char *lName, UNUSED const char
*rName, UNUSED const char *source, UNUSED const char *dest)

Can you give us a small testcase?
Thanks

With a simple testcase I cannot verify it:
struct A
{
void f(const int *, const int *);
};
void A::f(__attribute__((unused)) const int *i, __attribute__((unused)) const int *i2)
{
}
Are sure that UNUSED is defined to be the attribute?

A work around is to place the attribute after the variable name but this works only on 3.4.0 and above:
struct A
{
A(char);
};
A::A(char i2 __attribute__((unused)))
{}
