Package: gnubg
Version: 1.01.003-1
Severity: important

Dear Maintainer,
when I run gnubg, I get this error:

  This version of GNU Backgammon is compiled with SSE support
  but this machine does not support SSE

However, this machine does have SSE:

I first saw the issue when version 1.01.003-1 hit Jessie, and it wasn't
solved with version 1.02.000-1 (currently in Jessie). Prior versions
worked well. Root cause could be found in this change:

  * Drop special per-architecture handling of --enable-sse.  Upstream
    now probes for this during configure and at runtime and should do
    the right thing.

Well, apparently it doesn't!

Fixed as noted in 1.02.000-2, where all SIMD types are disabled for i386.
