Comment:
All patches, up to and including #23, are sufficient to both compile, and link,
the libgccjit shared library. However:
• The build fails immediately thereafter, due to an improperly specified
dependency, in the GCC Makefile; this is corrected by the trivial
24-libgccjit-full-driver-name.patch.
• Although the generated libgccjit shared library is, in fact, a Windows DLL,
it is named according to ELF convention, with a .so extension, and multiple
symbolic links to variously version-annotated alternatives; furthermore, no
accompanying libgccjit.dll.a, (as we would normally expect for a Windows
build), is created.
The latter failing is corrected by the attached
25-libgccjit-mingw-link-options.patch; this modifies the link command, for the
Windows build-case, to name the generated shared library as libgccjit-0.dll,
while also creating the libgccjit.dll.a import library, as a linker side
effect. Additionally, it modifies the installation commands, to install both
the DLL, and its import library, into appropriate locations.

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.
