* i386-tdep.c (i386_extract_return_value): If the type of the 

return value is TYPE_STRUCT and the number of fields is one, call
ourselves with TYPE set tp the type of the first field.
(i386_store_return_value): Likewise.
This fixes a problem with returning structs consisting of a single
`float' or `double' on *BSD.
