Can't the whole toolchain include ELF support as an alternative target? Kinda like "-m32" on x86_64. I don't think it's unreasonable to request that Cygwin provides this (and it'd probably solve other problems somewhere else). Have you tried asking the Cygwin maintainers what they think about that? -- Robert Millan I know my rights; I want my phone call! What use is a phone call, if you are unable to speak? (as seen on /.)
