This all looks normal.

No need to shout!

No. There is no need to do anything special with the compiler.

Its not clear where you are trying to build here. Are you building the
eCos library or your application? When building the eCos library the
build system will make sure the include paths are correct. For you
application code i suggest you look at the example makefiles. This is
part of anoncvs and you can also find at it:
