Can we use "ImportC" used yet?

Okay I'm definitely trying to use `importC` rather than the 
regular `extern(C)` way. I can see where I went wrong. The steps 
for importC for header files are:

1. Prepend the following directives to `test_og.c` or whatever 
your interface c script is:

#define __restrict restrict
#define __asm__ asm
#define __extension__
#define __inline
#define __builtin_bswap16
#define __builtin_bswap32
#define __builtin_bswap64

2. Run the commands:

gcc -E -P test_og.c > test_c.c
dmd test.d test_c.c && ./test

which works. Now I've tried the same thing with library `fftw3` 
and getting:

Error: undefined identifier `__float128`

Which I guess I have to define somehow in the original c
