Without -m32 I don't get the errors for the unsufixed constants even
with -pedantic-errors (I guess because sizeof(long long) ==
sizeof(long). I guess the test would work in 32bits targets without
-m32 but it will fail in 64bit targets.

I could restrict the test to 32bits targets with
require-effective-target ilp32 but then I cannot test it (I only have
access to x86_64)

What would be the dg-* magic to:

* enable -m32 for targets that support it and where sizeof(long long)
== sizeof(long)
* enable the test for targets where sizeof(long long) != sizeof(long)
* disable the test for the rest.

Cheers,

Manuel.
