Update of /cvsroot/dirac/compress/decoder In directory fdv4jf1.ch3.sourceforge.com:/tmp/cvs-serv2769/decoder Modified Files: decmain.cpp Log Message: Actually fix the issue addressed in (082d7a2) (ignored result from fwrite) Ubuntu forcibly enables FORTIFY_SOURCE, which warns on unused return values on fwrite. This may either be fixed by: #undef _FORTIFY_SOURCE #define _FORTIFY_SOURCE 0 Or, by causing the application to exit on a short write.
