[PATCH] Add missing include of windows.h in nl_langinfo.c

[Pavel Hrdina]

The commit fcfce839 improved localization of names for week days
and months, but the author forget to include windows.h in order
to use 'GetACP ()'. Without this header file build using mingw
fails with this error message:

../../../gnulib/lib/nl_langinfo.c: In function 'ctype_codeset':
../../../gnulib/lib/nl_langinfo.c:76:5: warning: implicit declaration of
function 'GetACP' [-Wimplicit-function-declaration]
     sprintf (buf + 2, "%u", GetACP ());
     ^
