Template based library is more difficult to precompile because cint DLL can
only include instantiated template class, not template itself.
Looking at number of header files, it is clearly a major work.

Let me first clarify that +P -p option and template are completely different
matters.
And now I want to discuss how to preprocess only for the RogueWave headers.
There are a couple of ways to do this.
1) use +P -P suboption.
Suppose you have a.h b.h c.h d.h, doing
$ cint a.h +P b.h c.h -P d.h
causes only b.h and c.h to go through formal preprocessor.
I'm not sure if rootcint supports the same.
2) Use #pragma preprocess
Using #pragma preprocess statement in header file , you can selectively
use preprocessor.
#ifdef __CINT__
#pragma preprocess RW/
#endif
#include "RW/defs.h"
#include "RW/aaa.h"
With '#pragma preprocess [prefix]' command, header file name start with
[prefix] are selectively go through preprocessor.
You already reported +P did not work. I'm afraid the problems do not
disappear only with the preprocessor.
