Windows and resulting char *trace

[Jeremy Cowgar]

On windows, C code get's added with an invalid escape sequence:

char *trace[30]={
  "C:\Development\Projects\Lisaac\compiler/make.lip (C:\Development\Projects\Lisaac\compiler/make.lip)",

I believe that the \ should either be escaped, or better yet, converted
to / as MinGW will handle / paths just fine on Windows.
