Hi,
I have a project aiming to old 68K processor. While I don't
think DMD would be able for this on the other hand I think GDC
can, am I right?
If yes would be any restriction of features to be used? Or the
compiler would be smart enough to handle this properly?

Potentially.
D is designed to only work on 32bit+ architectures. The 68k
series did have 32bit versions of them.
After a quick check it does look like LDC is out as LLVM has
not yet got support for M68k target. Which is unfortunate
because with the -betterC flag it could have pretty much out of
the box worked. Even if you don't have most of D at your
disposal e.g. classes and GC (but hey old cpu! can't expect
that).
I have no idea about GDC, but the -betterC flag is pretty
recent so its support may not be what you would consider first
class there yet.
At least 68030 (or 68020+68851) would be necessary for proper
segfault managing (MMU) and an OS that uses it. Afaict NULL
pointer derefernecing must fault for D to be "usable". At least
all code is written with that assumption.
