Compile error with default compiler on Gentoo

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Use Gentoo
2. python setup.py build

What is the expected output? What do you see instead?
Should just build. Instead I get the following error:

Using 
CXX=gcc-4.3.1 python setup.py build
works.

What version of the product are you using? On what operating system?
python2.5, llvm 2.4, llvm-py 0.5, Gentoo 2008.0

Please provide any additional information below.
I don't know if this is llvm-py specific, but maybe you can hard code gcc
so that g++ does not get used.

Correction:
Using
CXX=gcc-4.3.1 python setup.py build
does not work. It compiles cleanly, but the test cases don't work.

Traceback (most recent call last):

Could you try with both CXX=gcc-4.3.1 and the following change:

In setup.py, locate:

std_libs    = [ 'pthread', 'm' ]

and change it to:

std_libs    = [ 'pthread', 'm', 'stdc++' ]

and then try a clean build (remove the directory 'build' and recompile, or use
'setup.py build -f').

This issue is same as Issue #7. Since I don't have access to a gentoo system, 
any
help in fixing this would be much appreciated.

Both gcc-4.3.1 and gcc-4.2.4 work with your change.

r57 should fix this, please check. Now llvm-py should build with either gcc or 
g++.
