MJPEG Tools Svn

Added the patch provided by Salah Coronya

It fixes a segmentation fault with jpeg-7 and above where dinfo.do_fancy_upsampling isn't set by default to FALSE anymore.

The compare looks wrong to me, because the order of the iterators
is undefined. Suggest new code

for( std::deque<AUnit *>::iterator i = buf.begin(); i != buf.end(); ++i )

more solaris support.

Remove a couple more uses or references to __progname.

Seems some systems or development environs do not have __progname. argv[0] is fine for logging usage statements so use argv[0]

Solaris build patches submitted to the developer mailing list

Remove unused/not-needed _progname comment line.

Some versions of gcc added 'core2' in addition to 'nocona'. Apple's gcc 4.x
does not accept that option so workaround the new flag by doing a test compile
