need help with simple importC

[Dakota]

I am use importC from linux, get this error:


```sh
/usr/include/x86_64-linux-gnu/bits/floatn-common.h(214): Error: 
illegal combination of type specifiers
/usr/include/x86_64-linux-gnu/bits/floatn-common.h(251): Error: 
illegal combination of type specifiers
/usr/include/x86_64-linux-gnu/bits/floatn-common.h(268): Error: 
illegal combination of type specifiers
/usr/include/x86_64-linux-gnu/bits/floatn-common.h(285): Error: 
illegal combination of type specifiers
/usr/include/x86_64-linux-gnu/bits/floatn-common.h(285): Error: 
illegal type combination
```


from `floatn-common.h`
```c
#  if !__GNUC_PREREQ (7, 0) || (defined __cplusplus && 
!__GNUC_PREREQ (13, 0))
typedef float _Float32;
#  endif

#  if !__GNUC_PREREQ (7, 0)
#   define __builtin_huge_valf32() (__builtin_huge_valf ())
#   define __builtin_inff32() (__builtin_inff ())
#   define __builtin_nanf32(x) (__builtin_nanf (x))
#   define __builtin_nansf32(x) (__builtin_nansf (x))
#  endif
```

any tips to work this around ?
