C++ roadmap

[Luke Hutchison]

I tried the most recent Panama JDK 14 build with a C++ header file, and got
the following error message (in the form of a RuntimeException):

"Unknown type name 'namespace'"

I couldn't find a switch in the jextract commandline tool for enabling C++
support, so assume this means that C++ is not currently supported. I don't
see any mention of the lack of C++ support on the Panama "homepage" or
documentation, but I saw a claim somewhere online that Panama only supports
C, and has no real immediate plans to support C++. However, discussion in
the panama-dev archives seems to indicate that C++ support was always
planned.

Is there any experimental switch that will enable the use of C++ header
files right now in Panama? If not, what is the roadmap for C++?
