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.
Since _Bool is only ever a keyword and not a macro, and we can't
test for HAVE_STDBOOL_H in the headers, remove the #ifdef for it in
<cdio/types.h> and instead, simply define it as 'int'. Replace
inclusion of <stdbool.h> with <cdio/types.h> so that a consistent
definition of bool is used.
