I think this problem occurs becose -I- option used when compiling performed.
The -I- option happens on projects with the precompiled settings of an certain option.
Use "Project" -> "Properties.."
Under "Precompiled Headers" there is three strategies try picking diffrent one.
NOTE: The above assumes you are using projects, if not please try to use an project first.
Pardon Me, been up for about 24 hours making dumb mistake, Just deleted the mistake part.
