Dear Hermann-Josef,
Thank you for reporting the problem.
Bit-field limitation is just a warning. It should be OK to leave it as is.
Cint will ignore it by itself.
About /usr/include/bits/types, which contains many system dependent
symbols, I do not know why it is included either. Normally,
/usr/include/sys/types.h is included. There are a few things you
can try.
1) Create dummy header $ROOTSYS/cint/bits/types.h and see what will
happen. This file can be an empty file. If the system complains
about undefined symbol, add appropriate definition in this file.
2) Look at /usr/local/bits/types.h, there can be #ifndef XXXX to avoid
reading this file. You need to check what XXXX is in that file.
Add '#define XXXX' at the beginning of MiEvent.hh as follows.
#ifdef __CINT__
#define XXXX
#endif
Best Regards,
Masaharu Goto
