1065 that compilers are now clever, and share constant strings if they can.
1066 Elsewhere in Exim the string "<" is used. The compiler optimization seems to
1067 make use of the end of this string in order to save space. So the patching then
1068 wrecks this. We defeat this optimization by adding some additional characters
1069 onto the end of the string. */
