header - Notation I can't understand in Quake source code (C) -

i taking @ quake 1 gpl code , came across various similar header files, purpose or use of don't seem understand. tables of sorts , structured this

{1, 0}, {1, -1}, {1, -2}, {1, -3}, {1, -4}, {1, -5},[...] 

without before or after them. understand define i've never come across kind of notation in c. can read 1 of header files i'm referring here.

my question is: those...things? asm giving me less problems stuff.

these multi-use includes. can used so:

struct {int y; int y;} points[] = { #include <points.inl> };
