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.
- 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.

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.
