scons warning about duplicate environments

[GoogleCodeExporter]

i just pulled r792 and when sconsing i get:

scons: Reading SConscript files ...
Checking for C header file sys/mman.h... yes
Checking for C function sleep()... yes
Checking for C library v8... yes

scons: warning: Two different environments were specified for 
target src/gc.os,
    but they appear to have the same action: $SHCXX -o $TARGET

scons: done reading SConscript files.

i have no idea what that means, but it doesn't appear to be fatal.

Yeah, these appear in all combinations of gcc/python/scons versions. I believe 
they
are harmless, but I am currently not sure how to evade them :)

They seems harmless, yes. Building v8 doesn't generate them, though, so i 
suspect 
it's a project-local scons mis-configuration (i don't know scons (i'm a "make" 
addict)).

By the way: i'm investigating your project because i'd like to write a 
(new/second) 
back-end for my new JS messaging framework 
(http://code.google.com/p/jsonmessage/), 
and i'm excited about the possibilities i'd have with both the client _and_ 
server 
parts implemented in JS.

Happy hacking!

Commited in r793. Thanks a lot, this bugreport finally made me investigate & fix
these annoying warnings :)
