Fix the build with gcc when -Wredundant-decls is passed

Browse Source 
Summary:
gcc warns that `__throw_runtime_error` is declared both in `<__locale>`
and `<stdexcept>`, if `-Wredundant-decls` is passed on the command
line; this is the case with FreeBSD when ${WARNS} == 6.

Since `<__locale>` gets its first declaration via a transitive include
of `<stdexcept>`, and the second declaration is after the first
invocation of `__throw_runtime_error`, delete that second declaration.
