Ensure that src variable type to test mbsrtowcs is correct (#2735)

Browse Source 
When compiling with -Werror (./configure CFLAGS="-Werror" ...),
the test to see if mbsrtowcs exists
failed with pointer type of incompatible type, is char **, should be
const char **. It would proceed to assume mbsrtowcs didn't exist.
