    Both the avr and xa51 ports are unfinished and are effectively abandoned. While we could update them so that they compile and link with the current sdcc version, they won't be able to produce much useable code since they are incomplete.

    I am using a slightly older version "gcc version 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.1.00)" than you, but the build only fails as you describe only when using the --enable-avr-port or --enable-xa51-port configuration options. Since these ports are incomplete, I suggest you build sdcc without these options.

    Fellow developers: perhaps we should remove these configuration options?

    I have no problem with removing these configuration options.

    AVR and XA51 configuration options removed in svn revision #8094.
