I've used eclipse for years with java so these problems have been disconcerting. This is Eclipse Kepler Service Release 1.
I used cygwin (windows 7) because I already had it on my pc.
I updated my cygwin with the needed libraries: "gcc", "g++", "gdb", and "make".
I updated it because this:
#include <iostream>
using namespace std;
got errors (e.g. 'Symbol cout could not be resolved.')
The errors didn't go away.
Instead - even worse! - they are intermittent.
I now can run HelloWorld, then the errors reappear.
So I added a lot of specific paths to the include specification. Select "Project" menu ⇒ Properties ⇒ C/C++ General ⇒ Paths and Symbols ⇒ In "Includes" tab:
"Add" the following directories to "GNU C", where $CYGWIN_HOME is your Cygwin installed directory:
$CYGWIN_HOME\lib\gcc\i686-pc-cygwin\4.7.3\include
$CYGWIN_HOME\lib\gcc\i686-pc-cygwin\4.7.3\include-fixed
$CYGWIN_HOME\usr\include
$CYGWIN_HOME\usr\include\w32api
"Add" the following directories to "GNU C++", where $CYGWIN_HOME is your Cygwin installed directory:
$CYGWIN_HOME\lib\gcc\i686-pc-cygwin\4.7.3\include\c++
$CYGWIN_HOME\lib\gcc\i686-pc-cygwin\4.7.3\include\c++\i686-pc-cygwin
$CYGWIN_HOME\lib\gcc\i686-pc-cygwin\4.7.3\include\c++\backward
$CYGWIN_HOME\lib\gcc\i686-pc-cygwin\4.7.3\include
$CYGWIN_HOME\lib\gcc\i686-pc-cygwin\4.7.3\include-fixed
$CYGWIN_HOME\usr\include
$CYGWIN_HOME\usr\include\w32api
This did NOT fix it.
I notice from browsing around in the project properties that the old includes from my old cygwin install (before I updated it) are still in my project properties - even though these directories do not exist!
I get warnings like this during the build:
Invalid project path: Include path not found (C:\cygwin\lib\gcc\i686-pc-cygwin\4.5.3\include-fixed).
This directory was deleted and replaced by my cygwin update. It does not exist.
When I export the project settings this path is not included.
Where this path IS included under project settings:
Project Properties -> c/c++ General -> Preprocessor Include Paths -> GNU [C | C++] -> CDT GCC Build-in Compiler Settings Cygwin
Here you find lots of paths specifiying the paths under 4.5.3 which do not exist.
These can't be changed by me, it appears.
NOTHING that I do to clean, refresh, recreate indexes, close / open project or eclipse gets rid of these references to non-existent paths and these errors keep coming back.
What do I do?

The cygwin configuration in CDT was located in workspace path.
So, if you switch a new workspace path , CDT will refind the gcc and g++'s includes path.
These configurations was saved in the file "your workspace path\.metadata\.plugins\org.eclipse.cdt.core\language.settings.xml".You can change the value or replace with new workspace's file.
But you'd better switch a new workspace path to avoid other problem.
