See:

Relevant quote: "An announcement as to availability (post-IDL 6.1) [of
64-bit IDL for Linux] will be forthcoming following further
investigation."

I've heard lots of rumbling about getting a 64bit IDL for linux, which
could address some rather large chunks of memory, and perform long64
integer arithmetic at healthy speeds. Anyone have use for fast 64bit
integer arithmetic? Do 64-bit doubles ("double doubles") have any
appeal to anyone?
