-time

The (time the compiler) switch directs the compiler to display the
-time
elapsed time as part of the output information on each part of the compi-
lation process.

-Umacro

The (undefine macro) switch lets you undefine macros. If you specify a
-U
macro name, it will be undefined. The compiler processes all
macro) switches on the command line before any
switches.
You can invoke this switch by selecting the Undefines field in the
VisualDSP++ Project Options dialog box, Compile tab,
Preprocessor category.

-unsigned-bitfield

The
-unsigned-bitfield
the compiler to make bitfields which have not been declared with an
explicit signed or unsigned keyword to be unsigned. This switch does not
effect plain one-bit bitfields which are always unsigned.
For example, given the declaration
struct {
int a:2;
int b:1;
signed int c:2;
unsigned int d:2;
} x;
the values are:
