Build error: implicit declaration of function 'mtex2MML_free_string' is invalid in C99

[cj1128]

I got this error when building:

../../../../ext/mathematical/mathematical.c:104:5: error: implicit declaration
      of function 'mtex2MML_free_string' is invalid in C99
      [-Werror,-Wimplicit-function-declaration]
    mtex2MML_free_string(mathml);
    ^
../../../../ext/mathematical/mathematical.c:104:5: note: did you mean
      'itex2MML_free_string'?
../../../../ext/mathematical/lasem_overrides.h:12:6: note:
      'itex2MML_free_string' declared here
void itex2MML_free_string (char * str);
     ^

This basically makes the gem unavailable on macOS. Unless you have a workaround.

Hi! I’m working on a dissertation at the moment so I don’t have too much free time, but I will look at this when I get a chance.
