| std::ctype<char>::_M_widen_init() is a function authored by Jerry Quinn |
| <jlquinn@optonline.net>, which was added to libstdc++ with revision 74662 on |
| Dec 16, 2003 [1]. |
| |
| With permission from Jerry (thankfully received on Oct 9, 2012), we include a |
| copy of this function in the MADlib repository. The sole intention is to allow |
| compiling MADlib with recent versions of gcc while still keeping the runtime |
| dependencies limited to earlier versions of libstdc++. Technical details are |
| given in src/utils/libstdcxx-compatibility.cpp. |
| |
| 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 [2]: |
