Drat!

If you dump the symbols from the STL shared library on the system, is there one for `time_put` at all? If so, what is the mangled symbol it exports?

(As a perhaps terrible idea, could we use the `alias` attribute on a redeclaration to try to force to link against the correct mangling for Solaris only?)
