Please pardon me if this post is not helpful, but I as I was digging through the archives here trying to get up to speed with Boost.Build V2, I saw your comment about not knowing how to detect cygdrive. I just happened to be looking at the code for the cygwin version of mount and I was wondering if maybe this snippit might be useful:

From /usr/src/cygwin- 1.5.19-4/winsup/utils/mount.cc

/* show_cygdrive_info: Show the user and/or cygdrive info, i.e., prefix and
   flags.*/
static void
show_cygdrive_info ()
{
/* Get the cygdrive info */
char user[MAX_PATH];
char system[MAX_PATH];
char user_flags[MAX_PATH];
char system_flags[MAX_PATH];
cygwin_internal (CW_GET_CYGDRIVE_INFO, user, system, user_flags,
           system_flags);

/* Display the user and system cygdrive path prefix, if necessary
     (ie, not empty) */
const char *format = "%-18s %-11s %s\n";
printf (format, "Prefix", "Type", "Flags");
if (strlen (user) > 0)
    printf (format, user, "user", user_flags);
if (strlen (system) > 0)
    printf (format, system, "system", system_flags);

exit (0);
}
