[1] IRIX 6.5 inet_ntoa seems to break with GCC.
The following platforms are known to be deficient and will not work:
- Solaris 2.5 Lacks vsnprintf
+ Solaris 2.5 Lacks vsnprintf
+ TruUnix64 (DEC UNIX 4.0f) Lacks vsnprintf
Please don't report these problems unless you have a nice,
straightforward solution or workaround for them.
