Natalia Portillo f5f3c951bf Additional goes and woes in the VS projects to get it all to work together. 
snprintf definition should go in config.h
If Win32 is enabled and Joliet no, it fails. Joliet should be enabled.
vsnprintf definition should go in config.h
lseek64 is defined as _lseeki64 in Windows SDK.
types.h should go to correct place for manually created unistd.h in VS
Macros with arguments are defined differently in GCC than in VS.

The MMC5 spec says:

There is no requirement though that it *has* to and some DVD
drives like one by Thompson for XBOX don't support a
IOCTL_CDROM_READ_TOC for DVD's. So if we have a DVD we should not
prefer getting the TOC via MMC.
But on the other hand in GNU/Linux it is reported that using the
TOC via MMC gives better information such as for CD DATA Form 2 (used
in SVCDs). So if we *don't* have a DVD I think we want to try MMC
first.
Is this complicated enough? I could be wrong...
