1063 script that sets up a copy of Exim for running in the test harness. It seems
1064 that compilers are now clever, and share constant strings if they can.
1065 Elsewhere in Exim the string "<" is used. The compiler optimization seems to
1066 make use of the end of this string in order to save space. So the patching then
1067 wrecks this. We defeat this optimization by adding some additional characters
1068 onto the end of the string. */
