I realise that and only mentioned it as it came up here.

I'll try doing that, but why does:

gcc version 4.2.0 20060808 (experimental)

work. Have things changed with these libraries since last year. This
was, BTW, I relative new install of cyqwin. I just copied the gfortran
and gcc4 executables over from an older machine. I think this is a
cyqwin question.
