No. If I knew it included x86_64 (and other, maybe 32 bit archs) then I also
knew that the SNL code should not contain 'assign' declarations to 'long' or
'unsigned long', so I knew that the generated C code should be such that the
C-preprocessor/compiler should fail compilation. This is what I want to
test.

I am fairly certain that the snc code in question is correct and will always
produce an error, so it may seem that this test is not very important. But I
may not be the last person to work on this code, and someone else might
(erroneously) think they could simplify it. (This happens to me all the
time...) A regression test makes sure such a mistake becomes obvious pretty
fast.

Cheers
Ben
