flash_v2: packages/io/fileio/current/src/fio.h annotate

annotate packages/io/fileio/current/src/fio.h @ 1544:0071b7b58596

* src/fio.h: If no POSIX then CYG_FILEIO_DELIVER_SIGNALS and CYG_FILEIO_SIGMASK_SET call CYG_UNUSED_PARAM on their arguments to silence warnings. * src/file.cxx (rename): Use a throw specifier to match prototype.
