Bug#1104832: dune-istl: FTBFS: dune/istl/superlufunctions.hh:80:49: error: ‘::complex’ has not been declared

[Markus Blatt]

Hi,

thanks for the report.

I think that this is due to the recent upload of SuperLU version 7.0.1, 
which
might have removed the backwards compatibility that was there in 7.0.0 
and used
to fix a previous similar bug #1084252 [0].

They have removed the option to have the backwards compatible type complex
pointing to singlecomplex (introduced with version 7.0.0), see changes 
in file
SRC/slu_scomplex.h [1]

I'll create another patch here to use singelcomplex instead.

Amazing what the SuperLU guys manage to break between minor versions...

Cheers,

Markus
