Trouble Compiling Postgres 7.0.2 under Windows

Hi,

Would anyone be able to provide some assistance in why I'm getting these
errors when trying to compile PostgreSQL under Windows (NT/2000) using
Cygwin.

Version info: postgresql_7.0.2
cygwin v1.0 (latest non-beta version from Redhat/Cygnus)
cygwin32_ipc_1.03

IPC seems to work fine - I'm putting all the files in the right place (I
think), and ./configure runs without any errors.
When I come to make the binaries, I get the following errors, and make
terminates:

<snip>
make -C ../utils dllinit.o
make[2]: Entering directory `/postgresql-7.0.2/src/utils'
gcc -I../include -I../backend -I/usr/local/include -O2

make[1]: *** [../utils/dllinit.o] Error 2
make[1]: Leaving directory `/postgresql-7.0.2/src/backend'
make: *** [all] Error 2

I've bodged the dllinit.c file (which I'm sure isn't the right thing to do)
enough to skip the redfinition error, but then I get a link error:

<snip>

collect2: ld returned 1 exit status
make[1]: *** [postgres] Error 1
make: *** [all] Error 2

I can't find any reference to sys_nerr in the source so I'm a bit stumped
how PostgreSQL would compile?
Any pointers would be greatfully received.

Thanks,
Ol

P.S. Before anyone asks, I have followed the HOWTO/portNT instructions
which did get PostgreSQL to compile, but no further. They seem rather
convoluted (presumably because they're based upon the old Cygwin B20), and
are not very clear. Once I've got this working I'll write up the whole
procedure and stick it on the web - with appropriate 'thankyou's etc. of
course.
