The Alpha compiler generates the following code for 'char *foo = "XXXX";':

	.globl foo
.section        .rodata
$LC0:
	.ascii "XXXX\0"
.data
	.align 3
foo:
	.quad $LC0
	.ident  "GCC: (GNU) egcs-2.91.66 19990314 (egcs-1.1.2 release)"

...and the same code for 'const char *foo = "XXXX";'.

If you change it to 'char foo[] = "XXXX";':

	.globl foo
.data
foo:
	.ascii "XXXX\0"
	.ident  "GCC: (GNU) egcs-2.91.66 19990314 (egcs-1.1.2 release)"

...and if you compile the first version with -fwritable-strings:

	.globl foo
.data
$LC0:
	.ascii "XXXX\0"
	.align 3
foo:
	.quad $LC0
	.ident  "GCC: (GNU) egcs-2.91.66 19990314 (egcs-1.1.2 release)"

This is one of the subtle semantic differences between * and [].
