avr-gcc 11.2.0 with binutils 2.37 does not building

[Nick Clifton]

Hi Veit,

Starting with the 2.37 release we have changed the minimum C compiler
standard needed to compile the binutils.  With this release (and going
forwards) you will need a C compiler that supports at least the ISO C99
standard.  (Which is over 20 years old now...)

Cheers
