[BUG 1.7 getopt_long() and recv()] has problem for tftp-hpa-5.0 on cygwin-1.7/win2003

[Xiaoqiang Zheng]

to make the 2 BUGs more clear:

* in the while loop of processing options with '-' using getopt_long():  

$ tftpd/tftpd -u SYSTEM -L -vvvv -p -c -s /var/log

1. it seems the '-<x> <value>'(-u SYSTEM) argument pairs that pass the second argument as value have the value lost and the variable get null value. the '-<x>'(-L -p -c -s; -vvvv is a special one) type arguments that set some flag seems work well.

2. the value of 'optind'  is always 1 in each loop(-vvvv is a special one?). but it would have be increased by 1 in each loop.  after all the '-<x>' and '-<x> <value>' arguments being processed, its value. 

3. because the value of optind not increased 1 for each loop, so that the arguments '/var/log' at the end that pass value(s) get processed in a wrong way as the optind is used for 'argv[optind]' to set value to some variable(s).

* recv() returns -1 with error 14 when it read acknolege packet from the socket, the normal return value is 4.
