This is what we have as description: app-editors/emacs:wide-int - Prefer wide Emacs integers (typically 62-bit). This option has an effect only on architectures where "long" and "long long" types have different size. Seems that we copied the first sentence from Emacs' configure --help output, which also doesn't say anything about buffer size or memory footprint. > Also, I must say it sounds strange to me that you wait for user > complaints before you decide that some option should be on by default. Well, Gentoo may be a bit special there, as we leave the choice largely to the users. There are of course defaults (set in so-called "profiles") for the most important flags. But users _will_ complain if a default is completely unreasonable. Unrelated question: Are the "62 bit" in the description above correct, or should it rather be 61 bit? Ulrich
