MJPEG Tools Svn

Added the patch from the tracker:
https://sourceforge.net/tracker/?func=detail&atid=105776&aid=2924120&group_id=5776

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

about: pipelist.c: missing fclose()

it was postet original here:

amazing how each release of g++ manages to break code that's compiled for years.
seems g++ 4.4 had an issue with strrchr() at line 56
