Since this information is probably of general interest, I'm posting it:
#include <stuff> officially obtains definitions from the implementation,
while #include "stuff" officially gets them from source files (header
files) provided with the program.  <stuff> can actually be built into
the compiler, for example, and in general may not be something you can
conveniently add to.  There is no C-language requirement for anything
like the UNIX "cc -Iwherever" facility.
