I was just doing some coding on minor changes for hashcash-1.23 so I added a
-DCOMPACT options to remove extra cores and with that I get a stripped
example program (example.c) at 55kB.  I imagine it should be smaller still
as thunderbird itself will contain various things - presumably a replacement
from sdb, a SHA1 implementation etc.  Not even close to 16MB - where do
people pull these numbers from?

(I put the pre-release code at

it just includes a latest mingw compile patch someone sent me and minor
things - see CHANGES)

in the feature request to add hashcash in mozilla thunderbird,


which currently has status "WONTFIX", after i countered the arguments that caused it to get that status, the following happened:

i gave argument:

"this request is not about adding the 16 MB library, but about adding hashcash, which is simple and can be implemented in little size."

Ludovic Hirlimann then posted:

"Please provide a patch so we can figure out how much this would add and then decide if we want it in the product or not."

i'm asking hereby if someone can produce a patch to add hashcash to thunderbird, and post on there.
