PATCH for COLLECT2 (revised)

[Jason Merrill]

Can we use pexecute.c instead of conditionalizing the code in collect2.c?

Is it actually necessary to change / to \?  I thought DOS accepted both.

I don't think it'll work to do

  system ("cd foo");
  system ("do stuff in foo");

On Unix, at least, the first call has no effect.  I think you should
change the code to use chdir(3) instead.  That way you won't need to
conditionalize it.
