Eclipse tips for CDT

It is strange that new versions of eclipse are changing some important desirable behaviours and no doubt most of us spending more time to fix one after another. So following are few tips.

1. Indexing is not working or GC overhead limit exceeded: change memory size in eclipse.ini as following or even more if needed -Xms512m, -Xmx1024m and .XXMaxPermSize 256m
2. Content assist or ctrl+space is not working: Go to: Window->Preferences->C/C++->Editor->Content Assist-> Advanced and check "Parsing-based Proposals"

And don't forget to rebuild the index after above changes.
