For this and the other variables here, if we only need to refer to these in the
.cc file, make them file-scoped instead of private statics.

Also, static class members of non-POD type are banned.  You'd need to use a
char[] instead, or some other solution.

Most of them are referenced in unit-tests also. I changed to char[] instead of
string.
