Linux x86.

I'm trying to do with C/C++ the hot-swap that Java allows.

So, if GDB can't do it on its own, can we involve the compiler/linker
to make this happen?  Is there more complexity with C/C++ than with Java?

The section below of the doc talks about patching, but doesn't describe
a way to actually do it :-)
