Requiring 2.6 (final 2.6.0, not 2.6.0-test*) would allow, most simply, changing the arch_minimum_kernel defaults in sysdeps/unix/sysv/linux/configure.in to 2.6.0; that would get the benefits for any user configuring without --enable-kernel, although not the benefits of cleaner glibc internals. It would then be possible to clean things up incrementally: where __ASSUME_* macros are defined in kernel-features.h for 2.6.0 or before (or for 2.6.1 or before where the only reason for a 2.6.1 conditional is 2.6.0-test* kernels without the feature) they could be defined unconditionally (or conditional only on the architecture in some cases). And if a feature was present in 2.6.0 on all architectures, conditionals on the relevant __ASSUME_* in Linux-specific code can be removed, along with the macro definition if it's not tested outside Linux-specific code. -- Configure bugmail: http://sourceware.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
