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

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

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'

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.
