Just to clarify something, LGPL'd code is generally not suitable for
eCos applications. Because we do not use shared libraries, LGPL
requires that developers ship a complete set of object files to their
end users. That means not just object files for any eCos code, it must
include application code as well. Specifically, those end users should
be able to fix a problem with libmicrohttpd, recompile it, and then
rebuild the entire eCos application with the fixed library.

For many eCos developers the idea of having to ship any of their
application-specific code, even in object file format, is
unacceptable. Hence there is no LGPL code in the eCos repository.
Anybody thinking of using libmicrohttpd should think carefully about
the licensing implications.
