(pdrive_buf): New place to hold information about cygdrive. * fhandler_disk_file.cc (fhandler_cygdrive::set_drives): Store drive info in pdrive_buf since get_win32_name() could now be too small to hold everything. (fhandler_cygdrive::rewinddir): Reset pdrive to pdrive_buf. (fhandler_cygdrive::closedir): Ditto. * pipe.cc (fhandler_pipe::init): Be more defensive when referencing get_win32_name(). Rework logic which made a copy of the POSIX path and then never used it.
