[This was recorded as Debian bug#46993, cf.
http://www.debian.org/Bugs/db/46/46993.html]

Package: python-base
Version: 1.5.2-6
Severity: normal

On Unix systems, py_compile.compile() (and therefore compileall.py) won't
compile files with DOS/Windows lineendings (CR+LF). Commands like "import"
or "exec" will work, though.

The problem seems to be that py_compile.compile read()'s the whole file at
once and passes it as a string to __builtin__.compile(), while "import"
calls __builtin__.compile() for a file, so that __builtin__.compile seems to
do some magic while reading the file.

For a quick testcase:

  import __builtin__
  f=open("test.py","w")
  f.write('print "Hello"\015\012')
  f.close()
  f=open("test.py")
  c=f.read()
  f.close()
  __builtin__.compile(c,"test.py","exec")

results in:

  Traceback (innermost last):
  File "<stdin>", line 1, in ?
  File "<stdin>", line 9, in x
  File "<string>", line 1
    print "Hello"
                 ^
  SyntaxError: invalid syntax

while "import test" works fine and results in test.pyc.

Certainly the file.read() in py_compile.compile() isn't good enough for this
case.

Sorry, but I dont feel able to resolve this in time for 2.0 beta or final, so giving back to Jeremy to punt back off.  If post 2.0 is OK, give it on back!
