Subject: configure: test -std=c++11 before enabling unit tests
X-Git-Tag: v1.8.0~97^2
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=9c8ae2de7b6b37951ad3e75651784dcf02b1e0cb;p=libvpx

configure: test -std=c++11 before enabling unit tests

since:
77fa51003 Replace deprecated scoped_ptr with unique_ptr

the unit tests require a c++11 capable compiler; future versions of
googletest (1.9.x) will as well, so this change was inevitable if we
wanted to keep the snapshot up to date.
