Would this alternate version work (without requiring stdlib.h)?

(defun org-babel-C-ensure-main-wrap (body)
  "Wrap body in a \"main\" function call if none exists."
  (if (string-match "^[ \t]*[intvod]+[ \t\n\r]*main[ \t]*(.*)" body)
      body
    (format "int main() {\n%s\nreturn(0);\n}\n" body)))

Thanks,
