For code that is to be shared with real GRUB, we should only use GRUB's own functions, so there's no concern there. For util/ code, IMO we should be careful not to break other systems. GCC is widely available, so it's not such a big concern, but not so for Glibc. In general, I think we should avoid the complication of implementing two versions of our code (one with GNU-isms and one without) by only implementing the portable one. As for asprintf, I think unless/untill someone reports that it is missing on a system where GRUB is usable (i.e. where we have loaders for their kernel), we shouldn't worry about it. > But yeah maybe there's even in the kernel a use for asprintf, > so maybe a good idea to make a grub_asprintf? Probably not (because of space reasons), unless we find it terribly needed. But it's also possible to have it in real GRUB without having it in kernel. -- Robert Millan The DRM opt-in fallacy: "Your data belongs to us.
