Error compiling with nvcc

Compiling following program with nvcc:

```
#include
int main()
{
return 0;
}
```

Generates following errors:
```
./Imath/ImathTypeTraits.h:194:86: error: ‘type name’ declared as function returning an array
194 | template

Start with Imath/ImathTypeTraits.h around line 194 and reproduce the reported command, nvcc toy.cu -I /path/to/Imath/include/, using nvcc 11.5 and GCC 9.3. Investigate the reported template and lambda diagnostics; done means the sample including Imath/ImathTypeTraits.h compiles successfully with nvcc.
