Hello,
As time progresses, the ada-hurd.diff patch has now been living in Debian since
gcc-4.6 and is now in gcc-5 and gcc-6. Last try to get it included upstream was
in 2012, and 2014, e.g see
https://gcc.gnu.org/ml/gcc-patches/2012-06/msg01111.html
and follow-ups.
Maybe the time has come now for a proper inclusion of Ada/Gnat support in gcc-*
for GNU/Hurd. (Yes, I commit to maintain Ada in gcc for GNU/Hurd in the
foreseeable future, according to my abilities).
Attached is an updated patch, now living e.g. in GNU/Debian versions of gcc-5
and gcc-6.
Please tell me if you need a changelog entry too. And yes, I have already signed
all copyright papers for FSF wrt gcc (and other packages).
