What changed:
-------------
- Disable code which disallowed to start 32 bit Cygwin processes from 64 bit
Cygwin processes and vice versa. 32 bit processes are not recognized as
Cygwin processes by a 64 bit parent process and vice versa, so there is
no IPC other than what you have with non-Cygwin processes.
- Change magic number associated with process information block so that 32-bit
Cygwin processes don't try to interpret 64-bit information and vice-versa.
- Redefine content of mtget tape info struct to allow fetching the number of
partitions on a tape.
