gEDA-user: Specifications

[DJ Delorie]

They all look like "max bounds" and probably should use the pcb's
actual width and height instead.

A 32-bit signed integer type is what limits you to 1/4 mile (er, 0.338
miles).  If you need more than 0.338 miles on a side, yeah, you can
compile with long or "long long" but you'd have to go through and find
all the temps that are "int" and change them to "LocationType".
