+Normally, when producing DWARF 2 output, GCC avoids producing debug symbol 
+output for types that are nowhere used in the source file being compiled.
+Sometimes it is useful to have GCC emit debugging
 information for all types declared in a compilation
 unit, regardless of whether or not they are actually used
-in that compilation unit.  Sometimes this is useful, such as
+in that compilation unit, for example 
 if, in the debugger, you want to cast a value to a type that is
 not actually used in your program (but is declared).  More often,
 however, this results in a significant amount of wasted space.
