Package: ilmbase
Version: 1.0.1-1
Severity: minor

The testcase of ilmbase fails on Alpha with "upstream" compilers.
ilmbase needs to be compiled with the -mieee option on Alpha,
otherwise the testcase will fail.  In Debian gcc, we set -mieee by
default on Alpha, but this is not done in pristine gcc (or in the
gcc-snapshot package in unstable).  Hence, this failure is not
relevant in Debian, but it's still an upstream problem.

Here's some background on -mieee on Alpha:
