[avr-gcc-list] avr-gdb patches

[Russell]

Hi all,

I downloaded gdb-5.2.1.tar.gz and gdb-5.2-avr-0.0.patch from
  http://savannah.nongnu.org/download/simulavr/gdb-patches

After untarring to ~/gdb-5.2.1, i did:
  cp gdb-5.2-avr-0.0.patch gdb-5.2.1
  cd gdb-5.2.1
  patch -p1 < gdb-5.2-avr-0.0.patch

However, it says the patch has already been applied. Are these
avr additions standard in gdb now?

Can simulavr operate as a simulator without any hardware? Does
it simulate peripherals like the timer/counters and ports?
