That's an interesting and valid point.  My answer is basically that
the heroic complexities of conventional optimizing compilers aren't
really appropriate, and that something more Forthly is a better fit.
Others here have described what they do.

The abstraction inversion is unfortunate, but is inevitable if you
want Forth to run really well on a register machine.  There is a nasty
semantic mismatch that has to be solved somehow.

Well, if you want GC in Forth, you just use it.  There's no law in
Forth that says an application can't use GC.  It's not hard.

It's not, but then not many individual parts of GCC are in themselves
a big deal.  It has recurring costs, though, due to the downright odd
hybrid of LISP and C in which the machine descriptions are written.

Why would you write it in postfix?  If the pattern is naturally
prefix, that's what you'd use.

I'm just not a huge believer in strong typing; my preference is for
Smalltalk-style duck typing.  I don't really believe that typechecking
helps so much.  In GCC everything is a tree (or, later on, an RTX.)
People have suggested ways to use types a bit more in the compiler,
but nothing much has happened.  GC is really useful, but GC is not
language-dependent.

GCC can't really be used because it's not a library, just a batch
compiler.  LLVM may be easier, but my personal experience with it
isn't good: we had a project that used it, but it kept breaking and
the interfaces kept changing.  Also, the semantic mismatch between
forth and LLVM is large, and the work needed to interface it to Forth
would also be large.  Also, you'd have to get into this very large
chunk of software to fix bugs in it.
