Compiling 7.1.3 pgsql under cygwin 1.3 on W2000 errors

This is my first attempt at using cygwin so that I can try and compile
pgsql for Windows 2000.

pgsql source 7.1.3
cygwin 1.3.9
gcc  2.95.3-5
cygipc 1.09.2
Windows 2000 SP1

I followed the instructions about Win2000 installation of the postmaster at

http://people.freebsd.org/~kevlo/postgres/portNT.html

I had to re-download extra packages for cygwin after I realised there were
dependencies missing in the basic cygwin download.

Anyway I've now got to the point where the 'make' instruction writes errors
to STDERR, see below. nothing appears in /usr/local/pgsql/bin under the
cygwin directory.

I have tried the archives of this email-newsgroup but the server fails
sending me 'unavailable' after I try to search (archives.postgresql.org).

Any pointers on what I am doing wrong, would be much appreciated. I also
include output of configure process underneath (both STDOUT and STDERR).

Please let me know if I have to supply any other info to aid working out
the problems. Thank you in advance for any help you can provide.
