You need pcsc-lite header files to build pcsc_funcs.c, so I don't think
this exact requirement would be met, but it may be more feasible to make
a binary package that can be run both with and without pcsc-lite library
(.so/.a) being present.

Actually, Windows port of pcsc_funcs.c is already using LoadLibrary()
when built with MinGW, so something very similar is already present. I
would need to see a patch before being able to say whether it is
acceptable, but as far as this type of approach is concerned, I think it
would be feasible for 0.6.x branch.
