It turns out that in somewhere else 'R2' is defined in this constellation.
Since I don't know if and if yes where this define might be used I added a few lines before and after the template declarations.
Before:
{{{
#ifdef R2
#define __R2safe__ R2
#undef R2
#endif
/* here follow the template declarations using R2 as a template class name*/
[..]
#ifdef __R2safe__
#define R2 __R2safe__
#undef __R2safe__
#endif
