ODB needs GCC with plugin support. We make sure plugin support is
enable in MinGW GCC that is supplied with build2 (in the build2-mingw
package, though since build2 version 0.10.0 it is 64-bit only). Also,
since GCC version 9.1, the MSYS2 project started building their MinGW
GCC with plugins enabled.

So I would recommend that you use build2-mingw if you can (since that
is the version we test ODB with) or, if you must use the 32-bit version
for some reason, try GCC 9.1.
