Damir,
As you point out, <string> header file used by rootcint and by the compiler
are different. This causes problem when you compile dictionary.
g++ tries to compile dictionary generated by different header file.
There is no clean solution to this right now. I use a version from Modena
Software in rootcint and cint. While other people are implementing more
ANSI/ISO compilant version. Many of these are still evolving.
Please return 'char*' from MyMethod.
