mindycomp generates unusable module when source file is using Windows line ending

[phongphan]

Hi

Looks like mindycomp's lexer incorrectly emitting symbol with a trailing '\r' to make_token function, result in unusable module.

step to reproduct:

• convert line-ending of the file `libraries/dylan/strings.dylan' to Windows line-ending (CRLF).
• compile with mindycomp -ldylan strings.dylan

The result dbc file might be a bit bigger than the one that using Unix line-ending and cannot be load by mindy interpreter.

The bottom is the result from CRLF source file. The offending token is Dyland^M.
