All the characters between the angle brackets form the name of the
header, so <stdio.h> asks for a different header than < stdio.h >.
The mapping from this name to an actual file or built-in representation
is implementation defined, so an implementation is free to interpret
the second version by stripping leading and trailing spaces, and
end up with the same header as the first version, if it so chooses.
The names of the Standard headers do not include leading or trailing
spaces, so the correct form to use is <stdio.h>.

FallenAngel should get a better tutorial.

Ditto - this is off-topic, but I thought it worth an explanation to
complete the story. If anyone wants to discuss this further, please
do so in an appropriate forum or by private email.
