building postgres.exe ./configure dies

Hi folks,

I'm trying to build postgres 7.1.1 (or 7.1.2) on Windows NTW4SP6 using the
latest cygwin. The machine I am compiling on has a dual processor, PIII
configuration.

In the very first step, ./configure errors out!

>using CFLAGS=-O2

>configure: error: installation or configuration problem: C compiler cannot

This is using gcc version 2.95.3-4 (cygwin special). The exact same
problem occurs with postgres 7.1.2

Having never seen configure die like this, I am not sure what to do....

Is this a problem in the ./configure script (and if so what can I do), or
is this a problem with gcc (???) as the configure script would claim?

Where is this problem best reported? Here on the cygwin digest, or
somewhere in postgres land?

Thank you,

Jerry Asher
