/**
* @brief Initialize an internal data structure of ctype<char>
*
* This was previously an inline function and moved out of line with this
* commit:
* http://gcc.gnu.org/viewcvs?view=revision&revision=140238
*
* See also this bug report:
* http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37455
*
* std::ctype<char>::_M_widen_init() is a function added to libstdc++ by
* Jerry Quinn with revision 74662 on Dec 16, 2003:
* http://gcc.gnu.org/viewcvs?diff_format=h&view=revision&revision=74662
*
* With explicit permission by Jerry Quinn from Oct 9, 2012, we include a
* verbatim copy of _M_widen_init() here. However, a static_cast was added to
* avoid a warning.
*
* Revision 74662 of the libstdc++-v3 file include/bits/locale_facets.h, where
* std::ctype<char>::_M_widen_init() has been copied from, also included the
* following notice in the file header:
* http://gcc.gnu.org/viewcvs/trunk/libstdc%2B%2B-v3/include/bits/locale_facets.h?diff_format=h&view=markup&pathrev=74662

* As a special exception, you may use this file as part of a free software
* library without restriction. [...]
