How does GCC look for includes?

[Ivan Martinez]

	Hello all. Could you tell me how GCC looks for default include files?.
Does it always look in "/usr/include" or the directories are specified
in any configuration file?. When it looks in a directory, it doesn't
necessarily looks in its subdirectories, does it?. Many thanks.
