[PATCH] maint: avoid new syntax-check failure

[Jim Meyering]

I suggest to update maint.mk soon to the latest from gnulib,
mainly for its new check for the CVE-2012-3386 (make distcheck) bug.
Once you do that, you see a new "make syntax-check" failure,
triggered by this example from autoconf.texi:

    @example
    #if !HAVE_DECL_SYMBOL
    extern char *symbol;
    #endif
    @end example

    @noindent
    If the test may have not been performed, however, because it is safer
    @emph{not} to declare a symbol than to use a declaration that conflicts
    with the system's one, you should use:

    @example
>>  #if defined HAVE_DECL_MALLOC && !HAVE_DECL_MALLOC
    void *malloc (size_t *s);
    #endif
    @end example

Here's a fix for that that should be pushed first.
This probably counts as trivial, but I'll wait for an ACK.
