support for mac os x

[GoogleCodeExporter]

yaffs2utils_endian.c loads byteorder.h, which is linux only, and prevents from 
compiling.

ignoring the header seems to work on mac

#ifdef __MACH__ 
#else 
#include <asm/byteorder.h>
#endif /* __MACH__ */ 

I believe the equivalent functionality can be found in 

#include <libkern/OSByteOrder.h>

Which version of yaffs2utils are used?
Since I do not have the mac computer,
I can try to provide the patch to you and integrate it into 0.2 version.

Thanks.

Revision 21 can be build using the above patch as well as by adding:

#ifndef PATH_MAX
#define PATH_MAX 1024
#endif

below the #include statements in mkyaffs2.c.

The latest revision can not be compiled because MTD is not available on OS X.

Dear Benjamin:

Did you mean the file "mtd/mtd-user.h"?
The file "yaffs2utils_mtd.h" has been removed from the revision 25.
In my opinion, the files related to MTD should be included by using the header 
files of the tool chain (cross-build) or your local system(native-build).

About the "PATH_MAX" definition of OSX, I will fix it in the next revision.

Best Regards,

Dear Benjamin:

For the issue about PATH_MAX definition of OSX, would you try to include 
"sys/syslimits.h" to solve the problem? such as: 

#ifndef PATH_MAX
#include <sys/syslimits.h>
#endif

Thanks a lot.

Best Regards,
