982that compilers are now clever, and share constant strings if they can.
983Elsewhere in Exim the string "<" is used. The compiler optimization seems to
984make use of the end of this string in order to save space. So the patching then
985wrecks this. We default this optimization by adding some additional characters
986onto the end of the string. */
