build error in PeerDirect's patched POstgreSQL 7.2.1

Hi.

 I've tried to build  PostgreSQL 7.2.1 using PeerDirect's patch in latest
Cygwin on WinXP..

 Patch was successful, but  I've got following errors.

  $ patch < win32-port-newfiles.diff
  $ cd postgresql-7.4.2
  $ CC='gcc -mno-cygwin' CXX='g++ -mno-cygwin' ./configure
  $ make all

gcc -mno-cygwin -O2 -Wall -Wmissing-prototypes -Wmissing-declarations -I../.
