Re: [PATCH] LTO plugin for coff, part 1: break out ELF-specific code and enable COFF builds

Please explain why the existing --enable-lto switch is not sufficient.
The configure user API for LTO starts to look quite complex and
unorganized, with --enable-lto, --enable-lto-plugin, and
--enable-languages=lto.  Put another way, the poor user shouldn't have
to bother with the details, and will want LTO by default whenever
possible.

Thanks,
Ralf
