I was running 2.098, I have just installed 2.100.2, which does 
say that use of #include is not supported.
I have tried too to preprocess hello.c with `gcc -E`, but dmd is 
also unable to compile it preprocessed (with errors such as

/usr/include/stdio.h(246): Error: found `__filename` when 
expecting `,`

).
Is there any reasonably simple way to compile files such as this 
hello.c, or is it not ready yet? I'm not an experienced 
programmer, so I mostly want to know if I'm doing something wrong 
or if there's an alternative that doesn't require manual 
translations from C to D.
