Then I'd rather call it "linux-glibc" in this case. I'm really having a problem with conflating the kernel and the libc in fact. I'm fine with considering they are both "recent enough" but seeing that the linux target becomes totally unusable with uclibc, musl, dietlibc or any possible alternative is a concern to me. And the USE_DL, USE_CRYPT, USE_RT, USE_THREAD, USE_CRYPT_H are exclusively libc stuff and not related to linux itself. > 2.

I think I've been keeping them for a long time because I knew places where they were being used, and later just because it took more effort to remove them than to leave them. > If we really want to make it easy for users then we should add an > autoconf script Bah no thanks. You'll find another maintainer before we sink into this. I already hate its face beyond imagination as a user, I don't even want to meet its ass as a developer. I think it is the only tool ever created in computer history which has consumed more human time to work around than to write. > that automatically spits out a line with all the > supported options (and possibly `apt-get` commands to install the > remaining headers that are not supported). That's doable as suggestions for certain operating systems if needed, though history shows that such suggestions generally don't remain valid for a long time. In the mean time I've just added this to "make help" at the end : $ make help TARGET not set.
