Patch suggested by Kazuhiro Fujieda <fujieda@jaist.ac.jp>. 

* winsup.h: Add new macros sys_wcstombs and sys_mbstowcs.
        * syscalls.cc (_link): Replace calls to mbstowcs by call to
        sys_mbstowcs.
        * uinfo.cc (internal_getlogin): Replace calls to wcstombs and
        mbstowcs by calls to sys_wcstombs and sys_mbstowcs. Replace
        usage of constants by meaningful defines. Use result of
        GetSystemDirectory for HOMEPATH and HOMEDRIVE as a last resort.
