I'm not very familiar with the setup code, but I think I may have found the 
problem.  The function mkdir_p() in mkdir.cc contains the following, starting at 
line 99:

   for (c = path; *c; c++)
     {
       if (*c == ':')
	slash = 0;
       if (*c == '/' || *c == '\\')
	slash = c;
     }

   if (!slash)
     return 0;

If I understand this correctly, the function will return success without having 
created the leading directory if the path name contains a colon and doesn't 
contain a slash after the last colon.  I guess the assumption is that there is 
no "leading directory" to be created in this case.  [This part of the code was 
written in 2000, when a colon could not be part of a file name.]

I hope someone who understands the setup code better than I do can take a look 
at this.  I'm not confident that I understand all the uses of mkdir_p() or all 
possible reasons why its in_path argument might contain a colon.

Ken
