/* sprintf.c
*
* $Id$
*
* Provides an implementation of the "sprintf" function, conforming
* generally to C99 and SUSv3/POSIX specifications, with extensions
* to support Microsoft's non-standard format specifications. This
* is included in libmingwex.a, whence it may replace the Microsoft
* function of the same name.
*
* Written by Keith Marshall <keithmarshall@users.sourceforge.net>
*
* This implementation of "sprintf" will normally be invoked by calling
* "__mingw_sprintf()" in preference to a direct reference to "sprintf()"
* itself; this leaves the MSVCRT implementation as the default, which
* will be deployed when user code invokes "sprint()". Users who then
* wish to use this implementation may either call "__mingw_sprintf()"
* directly, or may use conditional preprocessor defines, to redirect
* references to "sprintf()" to "__mingw_sprintf()".
*
* Compiling this module with "-D INSTALL_AS_DEFAULT" will change this
* recommended convention, such that references to "sprintf()" in user
* code will ALWAYS be redirected to "__mingw_sprintf()"; if this option
* is adopted, then users wishing to use the MSVCRT implementation of
* "sprintf()" will be forced to use a "back-door" mechanism to do so.
* Such a "back-door" mechanism is provided with MinGW, allowing the
* MSVCRT implementation to be called as "__msvcrt_sprintf()"; however,
* since users may not expect this behaviour, a standard libmingwex.a
* installation does not employ this option.
*
*
* This is free software. You may redistribute and/or modify it as you
* see fit, without restriction of copyright.
*
* This software is provided "as is", in the hope that it may be useful,
* but WITHOUT WARRANTY OF ANY KIND, not even any implied warranty of
