Yes, it's a very well-known issue that the ECW code is ugly and
and far from being portable.


Similar issues were discussed on the list and reported:

http://trac.osgeo.org/gdal/ticket/1347
http://trac.osgeo.org/gdal/ticket/2032

Basically, types like UINT32 are not defined as well as plenty of extra 
qualifications around is used (ie. CNCSJPCBuffer::) in the code.
It's been patched [1] and reported [2] directly to ER Mapper
(and big thanks we got for that) but fixed version of code of
the library were never released by ECW implementor.
That's a shame, but we have to live with that, so I'd suggest you
to try to apply Daniel's patch [1]. It's a big patch, as the code is
broken in many places :-)

End of the Rant.
