[Gmsh] building of gmsh2

Hi

Thanks for your help. Now the compilation has been completed with no errors.

Then I have imported and meshed (2D) a step file of a quite large object. The 
visualization is very fast.

I have noticed that in the options/geometry/general there is the possibility 
to remove duplicate entities but only for the geo files.
I would like to perform a merging of coincident faces that are shared by 
different parts of a step file.  Possibly I would like to perform a similar 
operation also when the faces are not equal but have a part in common. In 
this case I would like to perform the merging of the common part only.

Thanks in advance for any advice
