I guess that, but that is really not a lot of information.

Better to share by modifying the repository directly.
There is a tool called
src/tools/flx_build_prep.flx
This prepares a new target for building. Please read
the code, its only short.
One of the switches to the tool is used to copy the C++ headers:
--copy-config-headers
This copies the headers in the source directory, usually
build/release/host/lib/rtl
The only ones of interest are:
~/felix>ls build/release/host/lib/rtl/*config.h*
build/release/host/lib/rtl/demux_sockety_config.hpp
build/release/host/lib/rtl/flx_pthread_config.hpp
build/release/host/lib/rtl/flx_demux_config.hpp
build/release/host/lib/rtl/flx_re2_config.hpp
build/release/host/lib/rtl/flx_exceptions_config.hpp
build/release/host/lib/rtl/flx_rtl_config.h
build/release/host/lib/rtl/flx_faio_config.hpp
build/release/host/lib/rtl/flx_rtl_config.hpp
build/release/host/lib/rtl/flx_gc_config.hpp
build/release/host/lib/rtl/flx_sqlite3_config.hpp
build/release/host/lib/rtl/flx_glob_config.hpp
build/release/host/lib/rtl/flx_sundown_config.hpp
build/release/host/lib/rtl/flx_manymouse_config.h
build/release/host/lib/rtl/flx_tre_config.h
[The other ones are actually generated from Felix source. Hmm .. didn't realise.
I should split these up]
Of those, most do not contain any actual configuration data.
Almost all the config data is actually in
~/felix>cat build/release/host/lib/rtl/flx_rtl_config_params.hpp

That's basically it. You have to set those macros.
I've actually been meaning to make a version of this file
for each platform and copy that based on a switch.
Most of the other stuff is not interesting if you're copying
C++ files to the target for building: it is only useful
if you're cross compiling, and require, for example,
libraries on your host to link to.
So really it's not a big thing to make your own Android config.
If you have a cross compiler, such as gcc with ARM target or whatever,
you could make code that runs on Android directly.
After all, Android is Just Linux with a Java based GUI on top.
If you want to do GUI stuff it is a pain on ANY platform!
Which is why I have played with SDL, since it allows one
to write portable graphics code (It's not a GUI, but is aimed
at games).
