VCARD_ATR_PREFIX is used as part of an array initializer so it should
not have () around it, so far this happened to work, but gcc-4.7 does
not like it.

This recent commit..

libcacard: fix reported ATR length

Broke the build on my OpenBSD (gcc 4.2.1) buildbot which was due to the
change to this macro.

Thanks for the report, my bad, used a different version of vcardt.h for
compilation probably. This breaks on linux as well with gcc 4.7.0 .
