Subject: [PATCH] Make 'writeUnitName' const-correct

Without this, an attempt to pass a string literal or an array of `const` `char` as an argument will create a warning:
* `warning: invalid conversion from 'const char*' to 'char*' [-fpermissive]`
* `warning: ISO C++ forbids converting a string constant to 'char*' [-Wwrite-strings]`

In a standard C++ environment, these warnings would be compiler errors.
