Description of the problem

CM.make somehow treats a backslash as a forward slash. This means that CM.make is unable to read any files that have a backslash in their name. For example:

• CM.make "\.cm";
  [scanning /.cm]

uncaught exception Io [Io: openIn failed on "/.cm", No such file or directory]
raised at: Basis/Implementation/IO/text-io-fn.sml:792.25-792.71

The problem is that CM is interpreting the backslash as a path separator (which it is on Windows). The interpretation of the argument probably should follow the system's conventions. ~ Note that there is a workaround, which is creating a wrapper CM file that uses a quoted path "\.cm".

Fixed for 110.99.3 and 2022.2.
