There is gcc version 3.4.4, and the Cygwin project provides a port of this version, which is what you appear to be using. But this is just one of many packages that the Cygwin project provides. When you talk about "the version of Cygwin" you're referring to the version of the posix compatibility layer that Cygwin provides (cygwin1.dll) which is currently at version 1.5.18. The gcc and binutils included with the Cygwin distribution are native. They only produces binares for PCs with x86 processors running Microsoft windows with Cygwin installed. They cannot be used for anything else, and have no idea about powerpc instructions. However, since Cygwin provides this posix compatibility layer it is common to build cross compilers in the Cygwin environment because it approximates a *nix machine for which the compilers were designed to be hosted on. This is normally done by downloading the source for gcc and binutils (and some kind of libc), and configuring them as cross compilers and then building them. This is the topic of this mailing list. So, if you have downloaded Cygwin from cygwin.com expecting to be able to do anything but build native binaries that run under Windows, then it will not work. You need to build a cross compiler yourself, or you need to download prebuilt binaries from some location such as a tool vendor (but not cygwin.com or any of its mirrors, because that is not the focus of the project.) If you do actually have a cross compiler installed, then you need to set $CC correctly (or your --host= configure parameters) because you are still invoking the Cygwin-packaged native gcc.
