What steps will reproduce the problem?

1. use gcc v4.5
2. Clean checkout of bleeding_edge standalone dart vm
3. cd runtime && ../tools/build.py --arch=ia32
    

What is the expected output? What do you see instead?

Expected output: sucessful biuld
I see:

What version of the product are you using? On what operating system?
Ubuntu 11.04, gcc 4.5

Please provide any additional information below.
It looks like the build was broken at r1679

See diff:

Apparently, const qualifiers before "uintXX_t* codepoints" are missing in
Dart_NewExternalString8
Dart_NewExternalString16
Dart_NewExternalString32

definitions in dart_api_impl.cc
