lib/timevar.c patch to avoid warnings on Solaris 8 + GCC 3.2

[Paul Eggert]

I installed the following patch to avoid warnings generated on Solaris 8
+ GCC 3.2 with --enable-gcc-warnings.

2002-10-19  Paul Eggert  <address@hidden>

        * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
        float, as this generates a warning on Solaris 8 + GCC 3.2 with
        --enable-gcc-warnings.  Instead, divide into 1.0 rather than 1;
        this generates a more-accurate value anyway.
        (timervar_accumulate): Rename local variables to avoid confusion
        with similarly-named global 'start_time'.
