Hello,

Ref: http://sources.redhat.com/ml/gdb/2004-09/msg00136.html
This patch performs a simple minded merge of lin-lwp.c into linux-nat.c.

With this change in place the task of switching to the inheritance 
target vector, and having a GNU/Linux specific target vector, become 
possible.

Tested on i386 FC3ish GNU/Linux with no regressions (as expected, this 
is a mechanical change).

ok?
Andrew
