+Mingw compilation support
+This is going to require quite a bit of restructuring.

+

+**Step-0**

+~~- [ ] Get FEXCore compiling with GCC~~

+- [x] Get FEXCore compiling with llvm-mingw

+  - Necessary instead of GCC path 

+  -  https://github.com/mstorsjo/llvm-mingw

+

+**Step-1**

+- [x] Move signal context construction to Loader side

+- [x] Drop frontend targets from cmake that won't ever compile with mingw

+- [ ] Remove Linux-isms from FEXCore side. Using wrappers where necessary

+  - This is a big one, quite a few things spread around the source code

+- [ ] JITs have some hardcoded assumptions here, might need to redefine some stuff so we can safely do some syscalls still

+- [x] Handle SIGBUS/SIGILL FEX requirements in frontend

+  - Requires a collaboration between FEXCore and FEX frontend to ensure nothing unexpected shows up as a signal frame 

+

+**Step-2**

+- [ ] Introduce Build CI so we don't break it

+- [ ] Introduce unittesting CI

+

+**Step-3**

+- [ ] Integration

+

+**Investigation**

+- [ ] How well does clang-cl or clang with a windows target work? Would be nice to not need to deal with gcc/mingw compiler problems.

+  - Initial testing showed linking problems that I couldn't resolve easily.
