The meaning of number in output of "gcc -E mycode.c"

[gan_xiao_jun@yahoo.com]

hi
I want to get information about precompile result.
And run
gcc -E mycode.c | tee result
in result, it have lines like follow:
# 234 ".../mycode.h" 2
after reading source code "c-ppoutput.c"
I think the 2 at the end means mycode.h is reread(if 1
then read first time)
But I am not sure the meaning of 234
I think this number is useful.
Thanks for any comment
gan
