Indeed, I suggested that.  I am hoping that we can isolate the ifdefs in these
"gdb_ptrace" functions (we should probably find a better name for those...), to
which you pass a "ptid" and do the right thing according to the current OS.  I
agree that adding ifdefs in the more complex code is ugly and less readable.

If my suggestion doesn't work well in practice, then feel free to revert to your
original solution, I certainly don't want to impose it if it turns out not to be
a good idea.
