Revision: 1015
Committed: Sun Oct 25 00:08:06 2009 UTC (14 years, 4 months ago) by michael
File size: 10808 byte(s)
Log Message:
- fixed broken cryptlinks as reported by henri
- removed deprecated inet_misc.c
- removed __attribute__ format, which sometimes really is usefull, even if
  unportable unless gcc, but for now they only give false warnings
