    Report compiler in -d -bV. Clang compat.


    Exim successfully builds with clang, albeit with a number of warnings.


     * Our %n usage in printf() calls appears to be correct and safe, AFAICT.
     * dummy functions are, unsurprisingly, unused
     * Valgrind macros cause vociferous complaints
     * Dynamic modules *not* tested


    Further clang testing on my part will require an OS update and clang
    2.9 to get -rdynamic support.
