[tyndur-devel] [PATCH] libc: fix variable x set but not used

[Andreas Freimuth <m.nemo@xxxxxxx>]

! posix/socket.c: verschluckt jetzt keine fehler mehr
* posix/getopt_long.c: nur von DEBUG-code genutzte variablen
  mit __attribute__((unused)) markiert.
* posix/regex/engine.h: nur von DEBUG-code genutzte variablen
  mit __attribute__((unused)) markiert.
- mmc_contexct.c(i386): entferne unbenutzten code
