Subject: Silence a warning from gcc 4.9.1.
X-Git-Tag: v8.2.0-rc1~193^2
X-Git-Url: https://gitweb.dealii.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=refs%2Fpull%2F100%2Fhead;p=dealii.git

Silence a warning from gcc 4.9.1.

The warning pertained to the fact that we define a function in an anonymous
namespace that is only called from a function inside an #ifdef ... #endif
block. The solution is to move the function into #ifdef ... #endif as well.

This addresses this test result: http://cdash.kyomu.43-1.org/viewBuildError.php?type=1&buildid=11683
