[En-Nut-Discussion] Ethernut with fix frequency

[Klaus Fetscher]

We have compiled the 3.01 sources with the define of NUT_CPU_FREQ. 
There was an error because "milli_ticks" was not defined.

\os\timer.c

#ifdef NUT_CPU_FREQ

#define cpu_clock   NUT_CPU_FREQ
#define delay_count (NUT_CPU_FREQ/4000)

#else                           /* !NUT_CPU_FREQ */

static volatile u_long seconds = 0;
static volatile u_char ms62_5 = 0;
static volatile u_long milli_ticks = 0; // -> Should be outside of the
#ifdef / #endif statement
static u_long cpu_clock = 0;
static u_short delay_count = 0;
static u_long NutComputeCpuClock(void);

#endif                          /* !NUT_CPU_FREQ */


I have put milli_ticks outside the #ifdef / #endif statement and now it
works.
