There are a lot of msvcp100 functions that look like they are unused:
* In string.c all of the MSVCP__String_base_*(), MSVCP_basic_string_*(), MSVCP_basic_string_wchar_*() and MSVCP_char_traits_*() functions, basic_string_w?char_replace_helper().
* In locale.c _Locinfo__Locinfo_ctor_bstr(), codecvt_{short,wchar}__Id_func(), collate_{char,short}__Getcat(), various ctype_*() functions, etc.
* In ios.c, the basic_istream_*() and basic_ostream_*() functions, ios_base_Index_func() and ios_base_Sync_func().
* In math.c a lot of std_Ctraits_{double,float,long}_*() functions.
Is it just that the spec file needs to catch up or that they will be used soon?
I attached a more precise list of the suspects. I did not actually verify that all of them are unused but based on the ones I looked at it seems to be the case.
If they are indeed unused and will remain so I can submit a patch to remove them.
