opensc fails on Rosetta: In function 'pcsc_to_opensc_error': error: 'SCARD_E_NO_READERS_AVAILABLE' undeclared

[barracuda156]

This is using a default gcc-4.2:

:info:build reader-pcsc.c: In function 'pcsc_to_opensc_error':
:info:build reader-pcsc.c:185: error: 'SCARD_E_NO_READERS_AVAILABLE' undeclared (first use in this function)
:info:build reader-pcsc.c:185: error: (Each undeclared identifier is reported only once
:info:build reader-pcsc.c:185: error: for each function it appears in.)
:info:build make[3]: *** [libopensc_la-reader-pcsc.lo] Error 1

And with gcc12 it fails on:

In file included from /usr/include/string.h:148,
                 from sm-iso.c:29:
In function 'prefix_buf',
    inlined from 'format_data' at sm-iso.c:234:7:

Ok, with --disable-strict this does not happen, but the build again fails on error: 'SCARD_E_NO_READERS_AVAILABLE' undeclared.

SCARD_E_NO_READERS_AVAILABLE error fixed in: ​https://github.com/OpenSC/OpenSC/commit/548a2036328a288d24a48797498c3f76d6e351ef See: ​https://github.com/OpenSC/OpenSC/issues/2596

gcc-4.2 still fails down the road with multiple errors, but gcc12 builds it fine.
