+19981029  libpq.a and psql.exe Version 6.4 for OS/2 
+---------------------------------------------------
+
+
+Requirements:
+
+emx 0.9c or newer under OS/2
+GNU crypt library for emx+gcc version 2.0.6 (available from 
+  ftp://ftp.leo.org/pub/comp/os/os2/leo/crypt/gnuufc.zip)
+
+
+Also a patch is needed for sys/socket.h around line 291.  The lines
+with the pluses need to be added, the other lines are already there
+and are only for reference:
+
+
+#define MT_IFADDR       13
+
++#ifndef MAXSOCKETS
++#define MAXSOCKETS 2048
++#endif
+
+struct mbstat {
+        u_short         m_mbufs;
+        u_short         m_clusters;
+
+
+Possible problems:
+
+  You will also need to #define TCPIPV4
+
+  Make sure both socket.a and ufc.a are linked in to the executable 
+AFTER libpq.a.
+
+The following include files will be needed in order to use the library.
+You only need to include one (libpq-fe.h) but these need to be present:
+
+postgres_ext.h
+libpq/pqcomm.h
+lib/dllist.h"
+c.h
+
+
+Good luck and enjoy!!
