Subject: Add some missing forward declarations.
X-Git-Tag: v9.3.0-rc1~367^2
X-Git-Url: https://gitweb.dealii.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a777a8dc2ddfc1773c15f50025e659c5fdb5c00a;p=dealii.git

Add some missing forward declarations.

These are functions for which explicit specializations exist in the .cc file. The
standard says that we need to forward-declare them. In practice, it doesn't matter,
but it did matter for an experiment I'm currently running that explicitly makes use
of the fact that these functions are specialized.
