--- Comment #2 from Paco Arjonilla <pacoarjonilla at yahoo dot es> ---
Here is another test case with macros.
```
#define MACRO(suffix) \
double operator "" _##suffix (long double arg) \
{ return arg; }\
double operator ""_##suffix (long long unsigned arg) \
{ return arg; }
MACRO(km)
MACRO(m)
MACRO(mm)
MACRO(µm) // <-- COMPILATION ERROR (should compile)
```
