These error messages refer to a prior declaration.

    cc: Error: /usr/local/src/emacs-21.1/lib-src/../src/regex.c, line 5836: In 
the definition of the function "regcomp", the promoted type of preg is 
incompatible with the type of the corresponding parameter in a prior 
declaration. (promotmatch)
        regex_t *preg;
