1065 /* This is a weird one. The following string gets patched in the binary by the
1066 script that sets up a copy of Exim for running in the test harness. It seems
1067 that compilers are now clever, and share constant strings if they can.
1068 Elsewhere in Exim the string "<" is used. The compiler optimization seems to
1069 make use of the end of this string in order to save space. So the patching then
1070 wrecks this. We defeat this optimization by adding some additional characters
1071 onto the end of the string. */
