/*
 * VARIANT test program
 *
 * Copyright 1998 Jean-Claude Cote
 *
 * The purpose of this program is validate the implementation
 * of the APIs related to VARIANTs. The validation is done
 * by comparing the results given by the Windows implementation
 * versus the Wine implementation.
 *
 * This program tests the creation/coercion/destruction of VARIANTs.
 *
 * The program does not currently test any API that takes
 * arguments of type: IDispatch, IUnknown, DECIMAL, CURRENCY.
 *
 * Since the purpose of this program is to compare the results
 * from Windows and Wine it is written so that with a simple
 * define it can be compiled either in Windows or Linux.
 *
 *
 * NOTES
 *	 - The Variant structure in Windows has a non-named union. This means
 *	 the member of the union are accessible simply by doing pVariant->pfltVal.
 *	 With gcc it is not possible to have non-named union so it has been named
 *	 'u'.  So it's members are accessible using this name like so
 *	 pVariant->u.pfltVal.  So if this program is compiled in Windows
 *	 the references to 'u' will need to be take out of this file.
 *
 *	 - Also the printf is a little different so the format specifiers may
 *	 need to be tweaked if this file is compile in Windows.
 *	 Printf is also different in that it continues printing numbers
 *	 even after there is no more significative digits left to print.  These
 *	 number are garbage and in windows they are set to zero but not
 *	 on Linux.
 *
 *	 - The VarDateFromStr is not implemented yet.
 *
 *	 - The date and floating point format may not be the exact same format has the one in
 *	 windows depending on what the Internatinal setting are in windows.
