/** \def BOOST_VMD_ASSERT(...)
\brief Conditionally causes an error to be generated.
... = variadic parameters, maximum of 2 will be considered.
Any variadic parameters beyond the maximum of 2 are just ignored.
The first variadic parameter is:
cond = A condition that determines whether an assertion occurs. Valid values range from 0 to BOOST_PP_LIMIT_MAG.
The second variadic parameter (optional) is:
errstr = An error string for generating a compiler error when using the VC++ compiler.
The VC++ compiler is incapable of producing a preprocessor error so when the 'cond'
is 0, a compiler error is generated by outputting C++ code in the form of:
@code
typedef char errstr[-1];
@endcode
The errstr defaults to BOOST_VMD_ASSERT_ERROR if not supplied.
It is only relevant for VC++.
returns = If cond expands to 0, this macro causes an error. Otherwise, it expands to nothing.
For all compilers other than Visual C++ the error is a preprocessing error.
For Visual C++ the error is caused by output invalid C++: this error could be
masked if the invalid output is ignored by a macro which invokes this macro.
