Thanks, we've already made some rearranagements and included a FIFO
patch with the same effect, so the following is the change against the
head of the main line.

Did you really mean to remove the test

AC_CHECK_LIB(iconv, iconv)

for all systems other than Cygwin?  As far as I can see if iconv really
is a separate library it will find the header, compile in the code, and
then fail to link.  However, I may be missing something.
