./configure fails on Winnt 4 SP 4

Hi all,

i've tried to compile V 7.0.3 on Windows NT SP4, using Cygwin 1.1.8,
PostgreSQL 7.0.3, cygipc-1.07-1.

I followed the instruction manual at
http://people.freebsd.org/~kevlo/postgres/portNT.html.

At point 7. the output of ./configure is:

administrator@AAC /usr/src/postgresql-7.0.3/src
$ ./configure

By the way, i've tried to compile sucsessfully a 'hello world' program
and it works.

Any ideas??

Thanks Andreas
