I am not terribly familiar with the rules of the preprocessor. Is it
the case that the expression of the BOOST_PP_EXPR_IF macro is expanded
regardless of the resulting value of the condition?
The reason I ask is because the following code produces a warning with
VC7 .NET 2003.
The warning is:
C4003: not enough actual parameters for macro 'BOOST_PP_EXPR_IIF_0'
The macro expands correctly.
Perhaps there is a better way to do what I am after. I would like to
create a comma separated list (no parenthesis as would be the case if I
only took the array data) from a possibly empty set.
