[opensource-dev] LGPL violation

[Erik Anderson]

There is a static component that is linked when linking to dynamic
libraries, however that is present mostly to inform the compiler on what the
ABI is, or how your compiled code is expected to interact with the DLL.  It
is very possible to write a piece of code that explicitly loads the library
by name and manually builds calls to it.  In fact, it's likely possible to
compile a program intended to run with a .dll without any related files
being on the machine at the time.
