Re-sending this as a reminder...

-------------------------------------------------------------------------

Hey all, 

now that upstream has already released glibc-2.27, we should think about 
getting glibc-2.26 stable soon. That, however, means work for all of us.

Typical problems:

* Build failures because xlocale.h is gone
  https://bugs.gentoo.org/638010
  Fix: include locale.h instead

* Build failures, undefined reference to 'minor' / 'major'
  https://bugs.gentoo.org/575232
  Fix: additionally include sys/sysmacros.h
  No, we can't delay this further; the inclusion is (finally) 
  also upstream gone in 2.28. Everything we fix now will for
  sure save us trouble later.

* Build failures because of missing rpc support in glibc
  https://bugs.gentoo.org/381391
  See the following wiki page for information:
  https://wiki.gentoo.org/wiki/Project:Toolchain/RPC_implementation

* Build failures because of missing NIS support
  After fixing rpc support, add a dependency on net-libs/libnsl
  (unconditionally).

* Some internal type definitions have changed, which may lead
  to more obscure build problems (rare).

Please test and fix bugs!!! 

If you want to update your otherwise stable system, please
keyword the following (otherwise you'll get blockers):

~sys-libs/glibc-2.26
=net-libs/libnsl-1*
=net-libs/rpcsvc-proto-1*

Feel free to try emerging sys-libs/glibc with FEATURES=test 
(that takes a while). On amd64/x86, nearly all of the ~4000 tests succeed; I 
know of the following problems:
* elf/tst-prelink-cmp fails, still needs analysis
* only with gcc-7.3.0, six tests math/test-?float128* fail (with my CFLAGS)
  This is a gcc regression (miscompilation of truncf128), already submitted
  upstream.
In any case, I think this still looks nice:
Summary of test results:
      7 FAIL
   4109 PASS
     11 UNSUPPORTED
     29 XFAIL
      2 XPASS
Other arches may show more test failures; please file separate bugs per arch;
see https://bugs.gentoo.org/634988#c1 for what is needed for a useful report.

Stabilization tracker (fresh and largely yet empty):
