Fixed pointer vs. va_list overloading problem occuring in gcc 3.3 (used for ARM build).

Fixed pointer vs. va_list overloading problem occuring in gcc 3.3 (used for ARM build).

It seems that when calling a method that has two overloaded versions like this:
  f(char* format, ...)
  f(char* format, va_list args)
with a second pointer argument: f("format", pointer), the second version is picked up.

I've found a description of a similar issue here: http://bugs.gentoo.org/63112

So, to resolve this ambiguity, I've named such LogMessageBuilder's Append functions differently.
