Unfortunately for the moment I can tell you exactly because I have access to a Windows PC only at work.
What I remember is that I ran "make" normally after "./configure" and I took note of the build command for the DLL so that I can re-issue the command by replacing glscblas with openblas. To capture the command I have redirected the make's output into a file. May be someone in the mailing list can suggest a more clean way of changing the way to build the GSL shared library. For the moment I cannot suggest anything better. Francesco
