__LINE__ macro expansion sporadically wrong due to line counter reset

[GoogleCodeExporter]

What steps will reproduce the problem?
1. run $ echo "void main() { int line = __LINE__;
line = __LINE__;
line = __LINE__; }" > line.cpp
2. run $ essl_to_glsl -o line.cpp

What is the expected output? What do you see instead?
$ g++ -E -x c++ line.cpp
void main() { int line = 1;
line = 2;
line = 3; }

$ essl_to_glsl -o line.cpp
void main(){
mediump int line = 1;
(line = 1);
(line = 2);
}

What version of the product are you using? On what operating system?
r705

Please provide any additional information below.
Add more line = __LINE__; lines to explore the exciting context-dependent 
nature of this bug.

This appears be to related to an incorrect __FILE__ increment:
$ echo "void main() { int line = __LINE__; int file = __FILE__;
> line = __LINE__; file = __FILE__;
> line = __LINE__; file = __FILE__; }" > line.cpp

$ essl_to_glsl -o line.cpp
void main(){
mediump int line = 1;
mediump int file = 0;
(line = 1);
(file = 1);
(line = 2);
(file = 1);
}

Alok: do you know if this is a problem in the new preprocessor?

Should be fixed in the new preprocessor.

Closing as fixed then.
