What compiler/switch is it that warns there?  It does not look like that 
particular compiler/switch is very useful.  sizeof(sal_uInt32) is a 
known, small integer at compile time.  It should be apparent to both the 
compiler and humans that it fits into the sal_uInt32 argument to 
rtl_crc32 without needing the static_cast noise.
