This patch updates the portfile for avr-gcc. It needs patch-avr-config-unknown-mcu.diff in files before building

gcc should error out if it encounters an unknown MCU. See gcc bug 45261.
comment:10 Changed 14 years ago by lars@…
I have attached two patches that can be used to update to gcc 4.5.2.
Installation
patch-avr-config-unknown-mcu.diff patches gcc. It needs to go into $(port dir avr-gcc)/files. Something like this:
sudo cp ~/Downloads/patch-avr-config-unknown-mcu.diff $(port dir avr-gcc)/files
patch-avr-gcc-update-452.diff updates the portfile for gcc 4.5.2. Apply with something like:
cd $(port dir avr-gcc) patch -p0 < ~/Downloads/patch-avr-gcc-update-452.diff
Background
For the background of patch-avr-config-unknown-mcu.diff, see http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45261.
Basically, gcc doesn't return with an error if it encounters an unknown MCU. This breaks the configure step of avr-libc.
Caveats
I have removed the other patches for avr-gcc without really understanding them. YMMV

What needs to be done to get Lars patches into trunk? They seem to be fine.
BTW: The patch patch-avr-config-unknown-mcu.diff is not needed anymore from gcc 4.5.3 onwards. See: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45261. It is fixed in gcc trunk revision 170536.

If I could, I'd close this ticket and link to #33107.
gcc 4.6.2 fixes at least one annoying bug (wrong const warnings for PROGMEM placed constants when using C++) over 4.5.2
(But here we are, ghosts whispering to each other in this deserted place.)
