[Gmsh] GMSH and OCC 6.3 with MinGW

[Joachim Zettler]

Dear all,
I think the GMSH development team is up to now the only group which
managed to patch the OCC 6.2 version to compile with mingw/cygwin in
Windows.
As I currently switched to the Qt SDK with Qt Creator and MinGW I also
need the OCC libs in a MinGW version.
Unfortunately I need the Version 6.3 of OCC libs to link with GMSH as
I use these libs for CAD graphics programming as well.
Can somebody help me in getting OCC6.3 to compile with MinGW?
I already tried the dumb way of using cygwin with -no-cygwin option
but at a certain stage in compilation process it fails with strange
compiler errors :(

Best regards in advance,
Joachim
