static link error on redhat 7.2

I tried to static link the libwww-5.4.0 on redhat 7.2
But I get such errors:

collect2: ld returned 1 exit status

And I found that:
# nm libwwwapp.a |grep HTZLib_inflate
         U HTZLib_inflate
# nm libwwwzip.a |grep HTZLib_inflate
00000498 T HTZLib_inflate

And I found that in HTZip.h:34
#ifdef HT_ZLIB
extern HTCoder HTZLib_inflate;
#endif

It seems there is something is not defined in ./configure?
Can anyone give an advise?
