The eclipse generator is an external generator... meaning that it uses
unix makefiles to compile in in linux with gcc. So, the project should
build properly, does it? If you go to the build directory and type
'make', does it build correctly?

The problem would still be present for the eclipse parser to support
the IDE browsing features. For example, it wil gray out the area when
it should not do so, etc. Is this what you mean by will fool the
parser?
