The error doesn't mean that the closing parentheses is missing from line
95, it means that the open parenthesis that it didn't match was the
"info" function on line 95.

If you want that then you need a backslash at the end of line 96, to
continue the logical line:

Make never looks across logical lines to complete variable or function
so you have to combine them into a single logical line with backslashes.
