                        POSTGRESQL BUG REPORT TEMPLATE
============================================================================


Your name		:	Todd Moyer
Your email address	:	tmoyer(at)arinc(dot)com


System Configuration
---------------------
  Architecture (example: Intel Pentium)  	:  IBM RS/6000

  Operating System (example: Linux 2.0.26 ELF) 	:  AIX4.2

  PostgreSQL version (example: PostgreSQL-7.0)  :  PostgreSQL-7.0.2

  Compiler used (example:  gcc 2.8.0)		:  gcc 2.7.2.3


Please enter a FULL description of your problem:
------------------------------------------------

Failed compilation:


bash-2.01$ gmake all
...

I had used the following configure command:
./configure --with-template=aix_gcc --without-CXX
--with-libs=/usr/local/lib


Please describe a way to repeat the problem.   Please try to provide a
concise reproducible example, if at all possible: 
----------------------------------------------------------------------

Both version 6.5.3 and 7.0.2 suffer this problem compiling with gcc
2.7.2.3 under AIX 4.2.
Version 7.0.2 compiles cleanly on AIX 4.3 with gcc 2.95.2.


If you know how this problem might be fixed, list the solution below:
---------------------------------------------------------------------

Copy and paste the values of FP_PLUS_INF and FP_MINUS_INF from
/usr/include/float.h into 
src/backend/port/isinf.c:

bash-2.01$ diff isinf.c.orig isinf.c
3a4,9
> #ifndef FP_PLUS_INF
> #define FP_PLUS_INF 4
> #endif
> #ifndef FP_MINUS_INF
> #define FP_MINUS_INF 5
> #endif

With this patch, the compilation is successful and most of the
regression tests pass.  (In particular, the float4 and float8 tests
pass).  Here's the regression test output:

bash-2.01$ gmake runtest

=============== Notes...                              =================
postmaster must already be running for the regression tests to succeed.
The time zone is set to PST8PDT for these tests by the client frontend.
Please report any apparent problems to ports(at)postgresql(dot)org

-------------------------------

I don't know if AIX 4.2/gcc 2.7.2.3 is considered a "supported" platform
or not, but I thought I'd pass this on in case it helps anyone else
out.  I know my solution is a hack, but it works well enough for me. :)
