I couldn't find jit-reader.h installed anywhere. I think it would be nice to install this. That way one could write a gdb JIT plugin without needing the gdb source tree.
This is a fair request. I am posting a fix soon.
BTW, I thought about starting a gdb-devel package, but decided to take the simpler path and just include this on the default GDB package. Maybe it is not the right thing to do; if that is the case, just let me know (Jan) and I will re-do it.
