Error: unrecognized file extension h

That's because recognizing h files caused Iain problems building gdc.

To deal with:

--- file.c ---
#include "file.h"

today I try use importC with libfuse3.

DMD64 D Compiler v2.106.0-beta.1

dmd -c fuse.c -Hf=fuse.di

I am not sure how to pass c flags into dmd here, and I can not find document about this.

try with:

clang -E $dir/fuse.c -o fuse.i -I./include -DFUSE_USE_VERSION=30

dmd -c fuse.i -Hf=fuse.di

It requires a little work before turning it into a .di (e.g. removing extensions) and then a little bit after (since the compiler generates code like `void someFunc(const struct someStruct* param1)`. But after a few seds and a small D script to remove declarations I don't care about, it actually wasn't too painful compared to using something like dstep which is a 50/50 gamble on whether it works, and is a much bigger pain to automatically clean the output of.
