* ios_compat.c:
*	The functions in this file allow object files that were created
*	with C++ 2.0 or C++ 2.1 to be linked with an iostreams library
*	compiled with C++ 3.0.  The type "seek_dir" is an enum defined
*	within the class ios, and its name in argument lists is different
*	in C++ 3.0 because of the new "nested classes" feature.
