The above is correct when building code to run on the target, such as libstdc++-v3. Code which runs on cygwin, such as gcc, has a host (and, in this case, build) of cygwin and a target of m68k-elf. Code which runs on the m68k-elf target, such as libstdc++-v3, has a host of m68k-elf and a build of cygwin (and no target, since libstdc++-v3 is not itself a cross-compilation tool). Ian
