How to convert C code for old Visual Studio 2005, especially the TinyExpr source code

I want to convert the source code of TinyExpr (https://github.com/codeplea/tinyexpr) in a C compatible code for Visual Studio 2005 ( I think it is C89/90 compliant). In particular I have a problem to convert this macro in ( present in tinyexpr.c ):

As I said in a comment there's really no nice way to do this in older compiler.

One possible way is to use a wrapper vararg function, which creates the array dynamically, call the real new_expr function, and then free's the temporary array.

The main reason I can think of is to make it easier to search for where that constant is used. For example, you search for e( instead of e.

That isn't the case here, however. The functions are being used, but not called explicitly.

The linked code contains an array of structs:

Support

TinyExpr supports addition (+), subtraction/negation (-), multiplication (*), division (/), exponentiation (^) and modulus (%) with the normal operator precedence (the one exception being that exponentiation is evaluated left-to-right, but this can be changed - see below).
