That's good to know. That means we have two possible solutions:

(1) Disable dtc in RSB for mingw64. Possible downside on version
incompatibility

(2) Figure out what they did to build it and mirror that patch into the RSB
recipe.
https://packages.msys2.org/package/dtc?repo=msys&variant=x86_64 appears to
be
the package so perhaps the answer is in there.

An easy workaround is to comment out dtc in rtems-default.bset and load the
mingw package.

Thanks for the info.
