Question about "#line"

When GCC tries to compile the following program:
#line 40 "../another_dir/xyzzy.c"
#include "incl.h"
it gives this error:
../another_dir/xyzzy.c:40: incl.h: No such file or directory
After some experimentation, I've determined that GCC is trying to include
the file named "../another_dir/incl.h", not "./incl.h" as I want. In other
words, if I first type:
ln incl.h ../another_dir
then everything will work fine. PCC does not exhibit this behavior -- it
always looks for the include file in the current directory, regardless of
any "#line" directives.
Which one is correct? GCC or PCC. The PCC version makes the most sense
(to me) but I don't know what ANSI says (if it says anything at all.) Does
anyone else know?
