Absolutely not true.  Directly from the gcc online manual:

"GCC looks for headers requested with #include "file" first in the 
directory containing the current file, then in the directories as 
specified by -iquote options, then in the same places it would have 
looked for a header requested with angle brackets. For example, if 
/usr/include/sys/stat.h contains #include "types.h", GCC looks for 
types.h first in /usr/include/sys, then in its usual search path."
