 As far as I know, that is a characteristic of the SPARC processor,
and cannot be

influenced by compiler directives. You *can* use byte-oriented
instructions on

data which is not on "natural" boundaries. I.e. you could access "lInt"
as follows

(from a packed array):
unsigned long int temp;
memcpy(&temp, &testdata.lInt, sizeof(temp));
printf("testdata.lInt = %lu", temp)
HTH -- Larry

does not print the right value. A pointer to an unaligned structure member results in a segment violation.
