Added check and symbol definition for WIN32 file API usage in configure,
supporting configure's --disable-largefile option for WIN32 targets also.
Non-configure systems which do not use config-win32.h configuration file,
and want to use the WIN32 file API, must define USE_WIN32_LARGE_FILES or
USE_WIN32_SMALL_FILES as appropriate in their own configuration files.
