A new version of the SDCC C compiler is available. You can use SDCC to develop for the Amstrad CPC, e.g. with using the SDCC Code::Blocks template or the programming tutorials by Mochilote. In the new version, there are a lot of optimisations for the Z80 backend, so be sure to update if you already use the old version. You can download it from http://sdcc.sourceforge.net.
