gdb-setq-thread-number

gdb-setq-thread-number is a compiled Lisp function in `gdb-mi.el'.

(gdb-setq-thread-number NUMBER)

Set `gdb-thread-number' to NUMBER.
Only this function must be used to change `gdb-thread-number'
value to NUMBER, because `gud-running' and `gdb-frame-number'
need to be updated appropriately when current thread changes.
