opensc @0.19.0_1 build fails with Xcode 10

[tgyurci (Teubel György)]

Due to changes in pcsclite.h, opensc @0.19.0_1 fails to build with Xcode 10:

...
  CC       libopensc_la-card-cardos.lo
In file included from reader-pcsc.c:41:
./internal-winscard.h:146:9: error: 'PCSC_API' macro redefined [-Werror,-Wmacro-redefined]

#define PCSC_API extern __attribute__((visibility ("default")))
        ^

Upstream has already fixed this issue:

Thanks for the report. While trying to fix this problem by incorporating that patch, I encountered a different one:

checking winscard.h usability... no
checking winscard.h presence... no
checking for winscard.h... no
configure: error: winscard.h is required for pcsc

This has been reported at ​https://github.com/OpenSC/OpenSC/issues/1486. I'm going to see if I can find a solution.

Issue has been fixed upstream in ​https://github.com/OpenSC/OpenSC/commit/c3bef7d5278c695f3778a629a720bdd8c3c42ce5

I checked and it fixed it for me.

This commit hasn't been included in a release yet. Perhaps add it as a patch for now?

Fixed. Sorry for the delay, but I really needed to fix the other issue because it made it impossible for me to build the port and I didn't want to do it "in the blind".
