I had issues trying to replicate the build process as per your 
[comment](https://github.com/brechtsanders/winlibs_mingw/issues/48#issuecomment-1044782237).

The first issue was that the git tag you said you checked out 
(*releases/gcc-11.2*) did not exist. That was easily solved with 
the following command: `git checkout releases/gcc-11.2.0` (did 
they change their release tags?)

The second issue was that the compilation of GCC did not work for 
version gcc-11.2.0 on my version of MinGW. Many of the configure 
flags resulted in warnings in the configure process since they 
were not recognized (should these flags be in the configure 
command?):

```
configure: WARNING: unrecognized options: --disable-bootstrap, 
--disable-werror, --disable-libgomp, --disable-libmudflap, 
--disable-libquadmath, --disable-libitm, --disable-libsanitizer, 
--disable-libstdcxx-pch, --with-arch, --with-gmp, --with-mpfr, 
--with-mpc, --with-isl, --enable-libphobos
```

Then I ran into an issue running the make command:

```
$ make -j12

HEADERS="auto-host.h ansidecl.h config/i386/xm-mingw32.h"

If we are going to try to get the package for GDC into mingw, we 
need to be able to reproduce the compilation process. Are the 
commands you gave in your comment not the actual commands you 
actually ran in your mingw installation? Are you using 
[MSYS2](https://www.msys2.org/)? If you are using MSYS2, which of 
the three x86_64 compiler toolchains are you using (clang64, 
mingw64, or ucrt64)?
