Already seen and tweaked in fact.

Hadn't seen those. I'll poke when it comes to that.

You wouldn't have a good glibc version to use for backward compatibility
anyway. (Unless you go and install something old somewhere temporarily).

Anyway, linux build now uploaded to
ftp://ecos.sourceware.org/pub/ecos/gnutools/ecoscentric-gnutools-sh-elf-20090121-sw.i386linux.tar.bz2

If that looks ok, I'll try and get a cygwin build going, but as I'm sure
you would expect, that will take longer.
