Bug reference:      2651
Logged by:          Remy Beaumont
Email address:      remyb@medrium.com
PostgreSQL version: 8.2 - beta 1
Operating system:   Solaris 10 on T2000
Description:        8.2 - beta 1 does now compile with Sun Studio 11
Details:

When we try to compile 8.2 - beta 1 on a T2000 wth Sun Studio 11, the build
fails at the following file:

make[5]: Entering directory
`/usr/home/remy/postgresql-8.2beta1/src/backend/utils/adt'
/opt/SUNWspro/bin/cc -Xa -xtarget=ultraT1 -fast -I../../../../src/include
-c -o float.o float.c
"float.c", line 112: identifier redeclared: cbrt
        current : static function(double) returning double
        previous: function(double) returning double :
"/usr/include/iso/math_c99.h", line 126
cc: acomp failed for float.c
make[5]: *** [float.o] Error 2


The flags used for compiling are:  CC=/opt/SUNWspro/bin/cc
'CFLAGS=-xtarget=ultraT1 -fast'

You need to find out why configure failed to detect that cbrt() is
available.

The cbrt function is not part of libc. It is located in the libm. Try
export LDFLAGS='-lm'

Yes, that is the next item on my list.
I'm just trying to compile it for now on a T2000 with the best
possible optimization.

With PG 8.1.X. I saw a 30% to 40% performance increase on sorts when
compiling with Sun Studio 11 and -fast.
