We only point out packages we know of and I don't know of anyone offering
win64 packages of curl. The download packages beyond the source ones are not
provided by the curl project but by friendly persons and organizations.

AFAIK, you can use the "generic" ones too.

Well, someone said you need a little tweak to build libcurl for win64 but I
haven't really got very much input on it:

libcurl builds and runs on more than 40 different OS and CPU combinations,
including a large amount of 64bit architectures. I can't see any reason why we
couldn't build and run fine on win64 as well.

But of course there may still be bugs and quirks since win64 seems to be a
very rarely used environment and I don't think very many people have used or
even tried libcurl on it yet.

Please build libcurl from source and help us by telling what changes you need
to do to fix the win64 problems you experience. It is a bit hard to fix
problems for systems you don't have with a problem desscribed as vaguely such
as yours.
