Stupid me! I was calling the subversion warning test *after* memory got

freed. Windows nicely crashes then.

Also: added human readable string in fileglobal, so you can check the
subversion in a file manually too. Rule:
- Find GLOB chunk (first chunk after REND now)
- skip sizeof BHead, 20 bytes in 32bits, or 24 in 64 bits
- there's 4 characters showing subversion, right now it reads "   1".
