But the index numbers SHN_LORESERVE to SHN_HIRESERVE have a special
meaning, eg. a st_shndx of SHN_COMMON means that the symbol is a common
symbol.  How would you distinguish that from a symbol in section number
65522?  The only way to do that is to skip the 256 logical indexes from
0xFF00 to 0xFFFF.
