I think using the same technique as with libmusclecard would be safe. As for the comment in the patch earlier... the problem is real and tested if there are multiple linkages of libpcsclite, but one as a static lib and another as shared lib (I remember dtlogin crashing.) It is safe if the multiple linkages are all dynamic.

SCardUnload is not part of winscard (Windows) API and then should not be exported. The correct solution would be to automatically call this function when the library is unload. I did not know the -zfiniarray=foo option and could not find an "official" documentation of it. Is it portable? Maybe a safer way to the use the same technique used by musclecard_fini() in /libmusclecard/src/musclecard.c Also note that calling this function may create problem as you noted in a previous patch [1] (see the comment in the SCardUnload() function). I don't know yet if this problem is real. Which solution do you prefer?
