OK, thanks.

When I compiling binutils, and find the compiler warning, then try to
fix it with other members. I have no environments, not familiar with
parisc, no enough time resources ... but I should still try my best.

Originally, I worked for coredump analysing (kdb for Linux kernel, gdb
for user mode C++ program) -- which have no test environments, either
not familiar many things, but the end time point is sensitive ...

At present, after I really touch the open source in details, I know:

 - Most of persons and companies (include me) have already get benefit
   from open source, especially fundamental software (e.g. binutils,
   gdb), but most of them do not contribute back to open source.

 - But open source still continue, and still benefit to most of persons
   and companies.

 - What I have done is just only try to contribute back to open source.


Thanks.
