Why is libgccjit need to depend on libintl anyway?
I guess, to provide internationalization of diagnostic messages.
gcc.exe and cc1.exe, for example, don't depend on it.
I'm puzzled, because that's not what I'm seeing here:

However, I do see that the version of gcc.exe in FRS is double the size of my
staged copy, and appears to be statically linked with both libiconv.a and
libintl.a, rather than with libiconv.dll.a and libintl.dll.a. I think I know
why, but I'd like to review the issue; the DLL dependencies were intended.

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.

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.
Our DLL version numbering scheme, like that also used by Cygwin, is based on
the libtool interface version numbering conventions; like Cygwin, we compute
the number, included within the DLL file name, as the libtool current version
number minus the libtool age. In this case, current would appear to be 10, but,
as David has indicated, ABI 10 is backwardly compatible with ABI 0, and every
version between. Thus, age would also be 10, and the appropriate current - age
result is, indeed, 0.
This stratagem was originally promoted by Charles (Chuck) Wilson, who
contributed to both MinGW and Cygwin; his rationale was to ensure that any
dependency on a specific version of a DLL could always be satisfied, through
backward compatibility, by the most recent release of that specific version,
but there was never any expectation, much less guarantee, that older versions
of any DLL would remain forward compatible with newer applications.
