there are 2 different standards for the 'B' series at work and this should be
decided with some better background information
ISO/DIN B5 paper is 176x250 mm^2 == 499x709 postscript points
JIS (Japan Industrial Standard) it is 182x257mm^2 == 516x729 ps points
JIS A series sizes A0 through A10 are identical to ISO/DIN A series sizes,
JIS B series sizes are not identical to ISO/DIN B series sizes. In fact JIS B
sizes are a tad over 6% larger than ISO/DIN B sizes. While ISO/DIN B sizes
can be cut from JIS B stock (with waste of about 5.7%), JIS B sizes cannot be
cut economically from ISO/DIN B stock.
I am not saying that the JIS numbers should be used, I am just saying that
someone at some point adopted the JIS standard and changing it now may have
some unexpected side effects and should be carefully considered.
As a sample side effect of this confusion, the simple latex file
does this break gv for you?
results in a ps with a BoundingBox that makes gv (3.5.8) on redhat linux with
any gs 6-8 segfault. Dooh!!!

In the end I still consider this a flaw in gv (shouldn't segfault from this).
