Comment:
As noted in the referenced mailing list thread, I've chosen to explore this,
with respect to the existing GCC-9.2.0 package set.
Having perused the relevant online GCC documentation, I note that I should
configure with --enable-host-shared, when adding jit to the --enable-languages
set. Since the principal effect of --enable-host-shared is to force generation
of position independent code, within shared object libraries, this seems kind
of redundant on MS-Windows, where code in DLLs is always position independent
anyway; however, without --enable-host-shared, the configure script rejects the
addition of jit to --enable-languages, so I configured as instructed. This
immediately led into the first jit build issue: with --enable-host-shared, the
generated libiberty object code is expected to reside in a libiberty/pic build
directory, but no such directory is ever built for --target=mingw32!
Initially, as stated in my first response to the mail thread, I kludged around
this, (on my GNU/Linux build host), by running 'cd libiberty; ln -s . pic'
after the make aborted, and then restarted make. Obviously, such kludges are
not satisfactory in any ultimate solution, so, drawing inspiration from this
patch set, as suggested in Eli's follow-up mail, I've implemented the attached
patch, to resolve this particular aspect of the issue.

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.

Comment:
Having resolved the libiberty issue described in my preceding comment, my
libgccjit build subsequently succumbed to the compilation failures, outlined in
this mail posting, viz.:
- GCC's jit sources gratuitously use dlopen(), but neglect to include
dlfcn.h; jit-common.h needs a patch, to work around this.BR - availability
of fchmod() is gratuitously assumed [in `jit-playback.c`]; a further patch
is needed, to use chmod() instead.

The attached patches, 22-libgccjit-win32-dlfcn.patch, and
21-libgccjit-win32-fchmod.patch, respectively address each of these issues,
allowing the jit code to compile, and thus taking us a step closer to a
successful build.
