[PATCH] 2.5.5-pre1 IDE cleanup

[Martin Dalecki <dalecki@evision-ventures.com>]

[-- Attachment #1: Type: text/plain, Size: 329 bytes --]

The attached patch does:

1. Kill two exports which mankind will never know what they where good for

2. Kill duplicated comments.

3. Kill declarations of never defined functions

4. Some other minor tidups here and there.

It is created on top of the other patches I already send to you however 
it should
apply independantly.
