Subject: Set optimization flags for ICC to -O1 in accordance with the findings
X-Git-Tag: v8.0.0~25
X-Git-Url: https://gitweb.dealii.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=14b5ef572a726369a2b1a2db2d3ae9931c530713;p=dealii.git

Set optimization flags for ICC to -O1 in accordance with the findings
here: http://code.google.com/p/dealii/issues/detail?id=30 . We may
revisit the issue at a later time, but for the moment this is the safe
approach.
