-> Hi. I'd like to update the ports list in the docs to include
-> references to v6.5 for the various platforms for which PostgreSQL-6.5b
-> has been tested.
+AIX 4.3.2 with native IBM compiler xlc 3.6.4 passes all regression tests.
+Other versions of OS and compiler should also work. If you don't have 
+a powerpc there might be differences in the geometry regression test.
 
-PostgreSQL 6.5.2 compiles and regresses ok on AIX 4.3.2 
-using the IBM compiler. 
-gcc has problems with shared libs that are not easily resolved.
+Use the following configure flags in addition to your own:
+./configure --without-CXX
+and if you have readline there:
+--with-includes=/usr/local/include --with-libraries=/usr/local/lib
 
-The following regression tests fail because of different rounding
-behavior or error messages: 
-int2 ..  failed		-- same as int2-i386-netbsd.out
-int4 ..  failed		-- same as int4-i386-netbsd.out
-geometry ..  failed	-- Some Zero Values with minus sign (-0)
-abstime ..  failed
-tinterval ..  failed
-horology ..  failed
+libpq++ does not work because xlC does not have the string and bool classes.
+compiling the few files, that fail, with g++ does work.
 
-It has the following problems:
+Compiling PostgreSQL with gcc (2.95.2) on AIX does work if you use the
+configure
+option: --template=aix_gcc 
 
-1. AIX has int8,int16,int32,int64 in /usr/include/inttypes.h 
-	--> configure fails to find snprintf support for int8 
-		(because it includes stdio.h)
-	I feel this is an IBM problem. I changed my /usr/include/inttypes.h
-	Either do that or comment out int8-int32 in src/include/c.h.
-	
-2. libpq++ does not work because xlC does not have the string and bool classes.
-	it does compile/work with gcc
+With the current compiler flags the redefines of int8 - int64 that prior
+versions
+had a problem with are not a problem any more.
