Btw, judging by the Info manual that comes with libgccjit, a more
appropriate name for the DLL would be libgccjit-10.dll, since it implements
LIBGCCJIT_ABI_10 (and the next versions of GCC advance the ABI by several
more notches). MinGW64 also calls it libgccjit-0.dll, so we could adopt the
same name, regardless. But then we will need to invent ABI numbers out of
thin air for future releases, which might be sub-optimal.
Upstream notes on API/ABI compatibility: https://gcc.gnu.org/onlinedocs/jit/
topics/compatibility.html
libgccjit hides all data layouts, and only ever adds entrypoints, so I've
avoiding bumping the SONAME, using symbol versioning instead, to allow for
backwards ABI compatibility. I'm not sure if that's going to work with mingw.

Ticket details:
Please add libgccjit to the binaries included in the MinGW GCC distributions.
This is required to be able to build projects that use libgccjit for JIT
compilation of code. One example of this is "gccemacs", a branch of GNU Emacs
development (soon to land on the master branch of Emacs) that compiles Emacs
Lisp programs into native x86 code for faster runtime performance.
Thank you.
