A long time ago ProjectCenter used to treat all compiler warnings as 
errors, I changed this last September. If your ProjectCenter code is 
older than this, you may just update it.
To make this very clear: The -Werror flag is a valueable tool during 
development, but should never be put in released makefiles, as you never 
can tell which warnings a different version of the compiler may give.
