Description: The definition of environ in stdlib.h is bogus and will not
work as it should. This is because the underlying
representation of the environment is not an arry of pointers.

Title: REMOVING PIPES AND FIFOS
Description: There is no way to remove a FIFO or PIPE created in the
pseudo filesystem. Once created, they persist indefinitely
and cannot be unlinked. This is actually a more generic
issue: unlink does not work for anything in the pseudo-
filesystem.
Status: Open, but partially resolved: pipe buffer is at least freed
when there are not open references to the pipe/FIFO.

Title: THE ARP ISSUES AGAIN
Description: The first GET received by THTTPD is not responded to. Refreshing the page
from the browser solves the problem and THTTPD works fine after that. I
believe that this is the duplicate of another bug: "Outgoing
[uIP] packets are dropped and overwritten by ARP packets if the
destination IP has not been mapped to a MAC."
Status: Probably closed. The basic ARP issue has been fixed (if
CONFIG_NET_ARP_SEND is enable), but this has not been verified
with THTTPD.
