Thanks for the changes pushed to sthibaul/hurd-builds so far (I realise 
there will be more to get it into a buildable state, e.g. the actual 
libpthread implementation).

General observations on mainly coding style issues that should be cleaned 
up for actual submission (there are also obvious issues with changes to 
non-Hurd-specific files needing cleaning up / justifying, which I didn't 
list individually):

* Avoid __GNU__ conditionals in generic files (as per Roland's comments on 
the TLS patch).

* Use <year>-2018 in copyright notices.

* There should be a descriptive comment on the first line of each file 
before the copyright notice.  Where you have such comments, make sure they 
don't say something is a generic version when actually it's a 
Hurd-specific version.

* Avoid FSF postal addresses in license notices; use a URL instead, as in 
existing files in glibc (using an https URL will avoid needing to be 
included in an http -> https fix for such URLs in future).

* No "Contributed by" notices in new files.

* verify.h should be LGPLv2.1+ for glibc use, but actually I think you 
should just use _Static_assert instead of verify.h, since the minimum 
compiler version for building glibc supports _Static_assert.

* sysdeps/mach/hurd/gai_misc.h needs a copyright / license notice (and is 
missing spaces before '(' in some places).

* In a few places, missing preprocessor indentation inside #if (as per 
<https://sourceware.org/glibc/wiki/Style_and_Conventions#Nested_C_Preprocessor_Directives>,
 
should be used except for a multiple include guard round a whole file).

* Why are some symbols added in sysdeps/mach/hurd/bits/posix_opt.h with 
value 200112L, when 200809L corresponds to the POSIX version generally 
supported by glibc?
