 K&R, 2nd edition, p211 last paragraph, last sentence: "Except that it
should diagnose explicit attempts to change const objects, a compiler may
ignore these qualifiers."

 This is very true, at least for the M68K assemblers that I know of. Nor
have I seen such a thing in x86 assemblers (less knowledge).
But: SECTION's (a program data/code "hunk" - in Amiga terms) can be set to
readonly - which _may_ be enforced depending on set assembler options (i.e.
to generate stuff for ROM).
