[vorbis-dev] Compiling with GCC on win32?

It needs a 64 bit type an int64_t is specified by POSIX and was supported by
SysV and BSD anyway.

It's meant to be compiled by a POSIX compiler, of which GCC is one.  In most 
cases, though, this is a header issue, not a compiler issue.

No, you need appropriate libc headers.

Sure, but this should be checked for in autoconf, not os_types.h, because there
are several million possible OS/Compiler/Header variation/combinations, and
we're not going to stuff them all in os_types.h.  That's for systems (like
win32) that nominally do not use autoconf.

Ah, this is Windows, OK.  Actually there has already been a proposed fix to 
the win32 entries in os_types.h to check for GCC and !UNIX...
