comment based on 'sys.args[0]' does not depend on the path. For Python
builds from a remote directory ("/path/to/configure; make") the previous
logic used to include the "/path/to" portion in Python-ast.h. Then svn
would consider this file to be locally modified.
Strip off leading dots and slash so the generated files are the same regardless
of whether you configure in the checkout directory or build.
If anyone configures in a different directory, we might want a cleaner
approach using os.path.*(). Hopefully this is good enough.
This change implements a new bytecode compiler, based on a
transformation of the parse tree to an abstract syntax defined in
Parser/Python.asdl.
The compiler implementation is not complete, but it is in stable
enough shape to run the entire test suite excepting two disabled
tests.
