compile net-snmp-5.7.1 under Cygwin reports error

'./configure' runs successful without problem, but when I try to 'make', it
just reports below error message:

I searched in Google without any luck, seems nobody has encountered the
same problem, or no one is compiling net-snmp in Cygwin now?

my Cygwin setup is as below:
CYGWIN_NT-6.1 Cygwin 1.7.9(0.237/5/3) 2011-03-29 10:10 i686 Cygwin

gcc version:
$ gcc --version
gcc (GCC) 3.4.4 (cygming special, gdc 0.12, using dmd 0.125)

If someone knows how to fix this problem, please kindly help me out of this
problem, thanks!
