Oops -- OK, sorry for the noise about that one. I'll update my kit.

I've attached the whole config.log file. The relevant portion seems to be:

  configure:1825: gcc -o conftest  -L/usr/local/lib   conftest.c -lz   1>&5
  configure:1848: checking for library containing iconv
  configure:1866: gcc -o conftest  -L/usr/local/lib   conftest.c  1>&5
  /tmp/ccc0H8V0.o(.text+0x1f):conftest.c: undefined reference to `_iconv'
  collect2: ld returned 1 exit status
  configure: failed program was:
  #line 1855 "configure"
  #include "confdefs.h"
  /* Override any gcc2 internal prototype to avoid an error.  */
  /* We use char because int might match the return type of a gcc2
      builtin and then its argument prototype would still apply.  */
  char iconv();

  int main() {
  iconv()
  ; return 0; }
  configure:1888: gcc -o conftest  -L/usr/local/lib   conftest.c -liconv   1>&5
  /tmp/ccy8e5Fc.o(.text+0x1f):conftest.c: undefined reference to `_iconv'

  /* Override any gcc2 internal prototype to avoid an error.  */
  /* We use char because int might match the return type of a gcc2
      builtin and then its argument prototype would still apply.  */
  char iconv();

  int main() {
  iconv()
  ; return 0; }

This one definitely seems to be a Cygwin-specific problem. The only
problem I saw on Debian was because I hadn't updated my libdbi install.
