Hey P. 

If you change this, you'll need to edit ldbl-extra.ver.

I see these kinds of exports on i486:
FUNC:_ZSt14__convert_to_vIdEvPKcRT_RSt12_Ios_IostateRKP15__locale_struct@@GLIBCXX_3.4
FUNC:_ZSt14__convert_to_vIeEvPKcRT_RSt12_Ios_IostateRKP15__locale_struct@@GLIBCXX_3.4
FUNC:_ZSt14__convert_to_vIfEvPKcRT_RSt12_Ios_IostateRKP15__locale_struct@@GLIBCXX_3.4

How are you going to deal with changing this?
