Compiling "test" program fails on gcc 4.7

[GoogleCodeExporter]

To be honest I do not know if this is a problem with gcc, shedskin, or my 
system. But I figure I will bring it up and let your decide. 

I have gcc 4.6 and 4.7 and when setting up shedskin I ran the test compile for 
the included test.py.  I have not used any custom flags etc. outputted code 
will compile fine under gcc 4.6 but fails to compile when using gcc 4.7. I have 
attached the output of running 'make' command, first with gcc 4.7 and then with 
4.6 to he give you an idea of what is going on and weather or not it is a 
problem with shedskin or not.

What steps will reproduce the problem?
1. python setup.py install
2. shedskin test.py
3. make

What is the expected output? What do you see instead?
The test binary, see attached. 

What version of the product are you using? On what operating system?
0.9.1
Ubuntu 12.04

thanks! it looks like I have some work to do for shedskin to work with gcc 
4.7.. :-) I will see if I can also install 4.7 under my 12.04 to have a look 
before the 0.9.2 release later this week.

couldn't figure out how to easily install 4.7 under 12.04, so I just had a good 
look at the errors. I think I just fixed the 'intptr_t' problem (for 4.7 it 
seems we have to explicitly include stdint.h).

will have a look at the other errors today.

alright, made two more changes which should hopefully avoid the errors for 
___min and __divs. could you try again please? :)

if these work, it seems there's still the problem of ::isatty not being 
declared. it's hard for me to look at this without 4.7, but it seems it's 
because unistd.h is included inside the 'std' namespace.. does it work for you 
if you replace ::isatty by std::isatty perhaps? and what happens if you just 
include unistd.h, without the namespace..?

O, you can easily install gcc4.7 in ubuntu using  ppa:ubuntu-toolchain-r/test 
(See https://wiki.ubuntu.com/ToolChain)

The command is, sudo add-apt-repository ppa:ubuntu-toolchain-r/test

I will pull and test your changes when I get a little free time (Hopefully this 
weekend)

ah, thanks for the command! I was able to test with 4.7 now, and made all the 
tests work in git.. :-) checking the example programs now..
