Casting a character pointer to uint16_t * or uint32_t * provokes this
warning on sparc. There is no actual problem, because all of the accesses
to data occurs through calls to the get_unaligned_*() functions, so this
commit suppresses the warning by using "void *" as an intermediate type.
All of these changes avoid using the same name for two local variables
within a same function. None of them are actual bugs as far as I can tell,
but any of them could be confusing to the casual reader.
The one in lib/ovsdb-idl.c is particularly brilliant: inner and outer
loops both using (different) variables named 'i'.
Found with GCC -Wshadow.
