It adds the following header to the HTML files:
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
which helps some browsers to display correctly the few non-ASCII
characters in the doc.
The flag was added to avoid excessive warning spam, but nowadays those
warnings no longer occur in such large numbers as to require silencing.
Besides, gcc-specific flags do not belong in the Makefiles.
These filters are designed for storing and transmitting video sequences
with alpha using higher-efficiency codecs such as x264 which don't
natively support an alpha channel. 'alphaextract' takes an input stream
with an alpha channel and returns a video containing just the alpha
component as a grayscale value; 'alphamerge' takes an RGB or YUV stream
and adds an alpha channel recovered from a second grayscale stream.

Avoid fastidious creation and immediate destroy of the display in case
one of the dither options fails to be set.
Also add NULL checks in write_trailer(), which are now necessary since
the function can be called when not all the components have been
initialized.
