Can D code be linked as part of C programs? e.g. can I write Apache module (dynamically linked .so file) using D? I wonder if that's a matter of sneaking in D's runtime, starting GC, etc., or is it not possible at all?

If you compile the D piece of your program as a lib, including its runtime, you should be able to link C code to it. You'll have to call the runtime startup/teardown functions yourself, but it should work. I'm pretty sure people have made Apache modules in D before.

It seems that DLL's a close to what I need (and I've found Apache module that uses them), but I'm not interested in Windows platform at all, I'm looking for Linux and OS X solution.

It's actually pretty simple to do so. For one, I know you can't use DMD on Linux to build SOs. You'll have to use either GDC or LDC. I don't know what the situation is on OSX, but perhaps DMD will build dylibs correctly there since Walter's done a lot more work on making it generate correct position-independent code. I have no idea, though. To build an SO, you more or less just build your library as normal, and just link it a bit differently. I think DSSS/rebuild will also insert the init/fini code necessary for setting up and tearing down the runtime when the SO is loaded and unloaded. That's probably your best bet.
