Only MSVC 2010 in x64 mode, in the static msvcrt, had a
stray log2 function (which wasn't available in the headers).

MSVC 2013 has got a proper log2 function though.

$cc is the compiler requested as main target compiler, while $_cc
is the actual tool tested in the probe function right now (which
can also be e.g. the host compiler).

This is printed in a separate subgroup "displaymatrix" inside a
new group named "sidedata". The subgroup has got two values,
"rotation" (which is the parsed rotation from the matrix) and
"matrix" containing the full actual values.

The option is enabled by default, but can be disabled.

If this is enabled, such side data isn't copied into the output stream
(except when doing stream copy).

This is enabled by default, but can be disbled via the -noautorotate
option.
