Hi,
as a response to my previous message i spent some time to find a solution to the problem. Googling around for a cross-Windows way to find the system drive letter reveals that the best approach is to query the 'windir' environment variable and extract the system drive letter from that. The good thing is that it can be done using standard C lib calls and the attached tiny C program demonstrates just that.
