Work around autotools setting C11 standard in CC/CXX
Work around autotools setting C11 standard in CC/CXX
In autoconf >=2.70, C11 is set by default for $CC
and $CXX
via the
-std=...11
flag. In this patch, we split the "-std" flag out of the $CC
and $CXX
variables, which we traditionally assume to be just the
executable name/path, and move it to $CFLAGS
/$CXXFLAGS
instead.
