[Gmsh] Compilation with gcc 6.1.1

[Martin Vymazal]

Hello,

  I'm getting the following error (svn revision 23170):

gmsh-source/Fltk/FlGui.cpp: In constructor ‘FlGui::FlGui(int, char**)’:
gmsh-source/FlGui.cpp:384:51: error: narrowing conversion of ‘128’ from 
‘int’ to ‘char’ inside { } [-Wnarrowing]
      0xff, 0xff, 0xff, 0xff, 0x00, 0x00, 0x00, 0x00};
                                                    ^
gmsh-source/Fltk/FlGui.cpp:384:51: error: narrowing conversion of ‘255’ 
from ‘int’ to ‘char’ inside { } [-Wnarrowing]
gmsh-source/Fltk/FlGui.cpp:384:51: error: narrowing conversion of ‘255’

gmsh-source/Fltk/FlGui.cpp:384:51: error: narrowing conversion of ‘128’

and then some more of the same kind. This can be fixed by changing

   static char gmsh32x32[] = {
     0x00, 0x00, 0x00, 0x00, 0x00, 0x80, 0x01, 0x00, 0x00, 0x40, 0x03, 
0x00,
     0x00, 0x40, 0x03, 0x00, 0x00, 0x20, 0x07, 0x00, 0x00, 0x20, 0x07, 
0x00,
     0x00, 0x10, 0x0f, 0x00, 0x00, 0x10, 0x0f, 0x00, 0x00, 0x08, 0x1f, 
0x00,
     0x00, 0x08, 0x1f, 0x00, 0x00, 0x04, 0x3f, 0x00, 0x00, 0x04, 0x3f, 
0x00,
     0x00, 0x02, 0x7f, 0x00, 0x00, 0x02, 0x7f, 0x00, 0x00, 0x01, 0xff, 
0x00,
     0x00, 0x01, 0xff, 0x00, 0x80, 0x00, 0xff, 0x01, 0x80, 0x00, 0xff, 
0x01,
     0x40, 0x00, 0xff, 0x03, 0x40, 0x00, 0xff, 0x03, 0x20, 0x00, 0xff, 
0x07,
     0x20, 0x00, 0xff, 0x07, 0x10, 0x00, 0xff, 0x0f, 0x10, 0x00, 0xff, 
0x0f,
     0x08, 0x00, 0xff, 0x1f, 0x08, 0x00, 0xff, 0x1f, 0x04, 0x40, 0xfd, 
0x3f,
     0x04, 0xa8, 0xea, 0x3f, 0x02, 0x55, 0x55, 0x7f, 0xa2, 0xaa, 0xaa, 
0x7a,
     0xff, 0xff, 0xff, 0xff, 0x00, 0x00, 0x00, 0x00};

to

  static char gmsh32x32[] = {
     "\x00\x00\x00\x00\x00\x80\x01\x00\x00\x40\x03\x00\
      \x00\x40\x03\x00\x00\x20\x07\x00\x00\x20\x07\x00\
      \x00\x10\x0f\x00\x00\x10\x0f\x00\x00\x08\x1f\x00\
      \x00\x08\x1f\x00\x00\x04\x3f\x00\x00\x04\x3f\x00\
      \x00\x02\x7f\x00\x00\x02\x7f\x00\x00\x01\xff\x00\
      \x00\x01\xff\x00\x80\x00\xff\x01\x80\x00\xff\x01\
      \x40\x00\xff\x03\x40\x00\xff\x03\x20\x00\xff\x07\
      \x20\x00\xff\x07\x10\x00\xff\x0f\x10\x00\xff\x0f\
      \x08\x00\xff\x1f\x08\x00\xff\x1f\x04\x40\xfd\x3f\
      \x04\xa8\xea\x3f\x02\x55\x55\x7f\xa2\xaa\xaa\x7a\
      \xff\xff\xff\xff\x00\x00\x00\x00"};
