How to reproduce. 
1. Change a C file in a subfolder of the project. 
2. Build. 

Expected result: 
Build only the changed file and the files that depend on it (from the dependency structure in the Makefiles). 
For instance this could be triggered by right clicking on a folder with changes and then selecting 'Build' or Eclipse used its internal information about dirty files. 

Actual result: 
Every single folder in the whole source tree is scanned for changes, although most of them contain no changes. This takes much time, more than necessary.

Having such an option would increase the development speed a lot. 
Thank you in advance.
