Subject: Fix FPE #include.
X-Git-Tag: v8.4.0-rc2~577^2
X-Git-Url: https://gitweb.dealii.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=refs%2Fpull%2F1402%2Fhead;p=dealii.git

Fix FPE #include.

We only need the #include if we actually use the functions the file
provides. Disable it otherwise to ensure that the tests continue to
run on platforms that don't provide <cfenv>.
