[PD] midifile

[Pall Thayer]

Here's the code I've edited:

// if PPC, define _BIG_ENDIAN

#define	_BIG_ENDIAN

/*#ifdef MSW
#define EXPORT_SHARED __declspec(dllexport)
#else*/
#define EXPORT_SHARED
//#endif
#define NO_MORE_ELEMENTS 0xFFFFFFFF

define MSW is commented out in the code so I would guess that my  
commenting out the ifdef MSW stuff doesn't really change anything.  
defining _BIG_ENDIAN  gives me the following warning:

midifile.c:30:1: warning: "_BIG_ENDIAN" redefined
<built-in>:1:1: warning: this is the location of the previous definition

Here's my line for compiling:

gcc -o midifile.pd_darwin midifile.c -bundle -bundle_loader ../bin/pd  
-flat_namespace (maybe this is wrong?)

It gives me a bunch of errors about signedness but from what i  
understand, they shouldn't really matter and it's a gcc4 thing.

Still always get the same error in PD when I try loading a midi file.  
The file plays fine in quicktime, so it's valid.
