I just tried it here with the 7.2.4 distro, and I get the same error as
Peter:

I'm not sure what's causing it to be honest, but as Hiroshi says, it
does look like it's trying to build an exe (hence the WinMain). I've
CC'd this to the Cygwin list - maybe Jason has an idea.

Regards, Dave.

Hmm I'm using /usr/autotool/devel/share/libtool/libtool.m4
on cygwin. Maybe it isn't the right one but seems to work
at least on cygwin.

A comparison of Hiroshi's output of the following:

    $ cygcheck -c | egrep auto\|libtool

to Dave's and Peter's should help to determine which versions work and
which don't

Yesterday, I was having trouble building anything
short of a hello.c, and I was getting similar
"undefined symbol WinMain@16" errors.  After hours of
fiddling, I finally ran the cygwin setup and figured
out that, at some point, I had unwittingly upgraded to
binutils-20021107-1.  There was a second release
available, binutils-20021107-2, which I promptly
updated, along with some other packages.  My problems
magically disappeared.  I wish I could be more
specific, but I don't think it's going to happen.
Based on file dates, I believe I updated the following
packages:
binutils
gcc
login

I don't know how helpful this information will be, but
I figured I would try.

I think that you hit it on the head!

    http://cygwin.com/ml/cygwin-announce/2002-11/msg00007.html

Dave, Peter, if you have binutils 20021107-1, then please upgrade.

I was already using the -2 release.

I was able to build psqlodbc-7.2.4 using the following Cygwin
development tool versions:

    $ cygcheck -c | egrep 'auto|libtool|gcc|binutils'
    autoconf            2.53-1
    autoconf-devel      2.53-1
    autoconf-stable     2.13-4
    automake            1.6.2-1
    automake-devel      1.6.2-1
    automake-stable     1.4p5-5
    binutils            20011002-1
    gcc                 2.95.3-5
    libtool             20020705-1
    libtool-devel       20020705-2
    libtool-stable      1.4.2-2

As you can see, I have not upgraded to the latest versions (for various
reasons -- some good, some bad).  Sorry, that I can't be more helpful.
