New issue 1890 by address@hidden: Compiler warnings in make
http://code.google.com/p/lilypond/issues/detail?id=1890

Our discussions about GOP PROP 5 (make) led to the conclusion that compiler  
warnings are not desirable and can point to potential bugs.  My recent  
builds have shown about 195 warnings, so I'm opening this issue to allow  
these to be considered.  This is on 64 bit ubuntu - not sure if that's what  
is causing some of these.
