[Gmsh] 2D boundary layer mesh

Hi to everybody!
I need to mesh a 2D multiflapped wing section, and I have to import it 
in OpenFOAM, so I need to extrude it in the spanwise direction with one 
single cell, in order to do a 2D calculation.
I'm having problems in generating the boundary layer mesh, as the  
extrude{surface{}}  command do not works with lines (extrusion of lines 
in normal direction),  and seems that I cannot use extrude{surface{}} if 
my domain is for example a square with an hole, like this:

__________
|                   |
|      __         |
|      |_ |        |
|__________|

(The hole pass run through the whole domain).
Anyone has an idea on how to mesh something like this?
Thank you,
Ivan
