+1.10)   How do I install PostgreSQL V6.3 under Irix 6.x?
+
+        Irix 6.2-6.4 has a bug in ld which mishandles the addresses of
+        static procedures when object files are assembled into
+        larger object files using 'ld -r'. This bug has been reported
+        to Silicon Graphics. 
+
+        Depending on your Irix installation you may also encounter
+        2 other problems detailed below: Conflict in C standards,
+        Conflict in library functions.
+
+        a) Solving the ld bug
+        ---------------------
+
+        One option is to use the Gnu version of ld. Alternatively,
+        the following patch should be applied as a workaround. 
+        (Supplied by Bob Bruccoleri <bruc@bms.com> and modified for
+        PostgreSQL V6.3 by Lasse Hiller Petersen <lassehp@imv.aau.dk>)
+
+        Apply the following patch:

+
+        Lasse configured with ./configure --enable-locale
+        and modified Makefile.custom to contain:
+CC = cc -n32
+LD = ld -n32
+        
+        He reports that the installation without -n32 works fine too,
+        but the -n32 was required for compatibility with his Perl
+        installation. His system was an Origin200 running IRIX64 v6.4.
+
+
+        b) Conflict in C standards
+        --------------------------
+
+        I have found that the following patch is also necessary in order
+        to prevent a duplicate definition of a Union used for semaphores.
+        Apply the following patch to:
+        .../src/makefile/Makefile.irix5:
+
+*** src/makefiles/Makefile.irix5.orig   Thu Mar  5 16:59:58 1998
+--- src/makefiles/Makefile.irix5        Thu Mar  5 17:01:13 1998
+***************
+*** 6,9 ****
+  %.so: %.o
+        $(LD) -G -Bdynamic -shared -o $@ $<
+
+!
+--- 6,9 ----
+  %.so: %.o
+        $(LD) -G -Bdynamic -shared -o $@ $<
+
+! CFLAGS+= -U_NO_XOPEN4
+
+        i.e. the addition of the line:
+        CFLAGS+= -U_NO_XOPEN4
+
+        This is needed to stop the semun union being redefined in
+        /usr/include/sys/sem.h
+
+        c) Conflict in library functions
+        --------------------------------
+
+        In addition, if you have the nsl and crypt libraries these will
+        conflict with the required definitions. I think that libnsl.a
+        may be the Netware socket library (or something similar). In
+        any case, if you have these libraries, they will be added to
+        Makefile.global and you will need to remove them.
+
+        Thus, you should edit .../src/Makefile.global. Goto (approximately)
+        line 217 where LDFLAGS= is set and remove -lnsl and -lcrypt
+        from this line.
+
