I am now trying to use it under Windows and running in the error below. I've worked around the issue by changing property.jam (see the last commit of https://github.com/tee3/build/commits/devel-workaround-for-possible-windows-bug), but I'm looking for a real fix wherever it needs to be.

This isn't exactly a bug. The problem is
the following definitions in tools/types/exe.jam.
(There are probably similar definitions for obj
and lib)

type.set-generated-target-suffix EXE : windows : "exe" ;
type.set-generated-target-suffix EXE : cygwin : "exe" ;

On Windows, this also matches, and Boost.Build has no
way to know that your definition should take priority.
The easiest workaround is to add a definition that specifies
both your toolset and windows to disambiguate.

@swatanabe Thanks so much, that is a better workaround than changing Boost.Build.

However, the truth is that the target-os for this toolset is really bare-metal (or maybe coff or elf or something like that) and definitely not ever windows. I see now that I'm building for target-os = host-os since that is the default behavior. Do you think a better longer term answer for this toolset is to only allow it to work for a compatible target-os?

For others, the change to the toolset was something like the following:
