Using strcat might only have the effect of avoiding the warning,
while retaining the portability problem,
which may or may not be acceptable to you.

If you actually want the portability that the warning is reffering to,
and if latexwrapper is supposed to be constant,
and all that you are ever going to do with it, 
is to write it to a file 
or to files such as standard output for example,
then you might try something like
   static  char latexwrapper[33][510] = /* {"",""} */
and use fputs in a loop to do write operations
on 33 strings of acceptable length.

The number (509) appears more than once 
in the C90 standard 
in a related context.

ISO/IEC 9899: 1990

7.9.6 Formatted input/output functions
7.9.6.1 The fprintf function

Environmental limit
    The minimum value for the maximum number of characters
    produced by any single conversion shall be 509.

G.2 Undefined behavior
    — A single conversion by the fprintf function 
      produces more than 509 characters of output (7.9.6.1).
