[Quantlib-dev] Re: Bug#314650: quantlib: FTBFS (amd64/gcc-4.0): 'Observer' has not been declared

[Dirk E. <ed...@de...>]

Andreas,

Thanks, as always, for your gcc 4.0 patches. I am passing this on to the
quantlib-dev listm and I'm sure that the simple patch will find its way into
the CVS archive.

Regards, Dirk
