16. S. While this is on 10.6 ppc, I am pretty sure the error is unrelated to it being a developer build and can be reproduced on 10.5.8 and 10.6.8.

It should probably do something like:

#if defined(__i386__) || defined(__ppc__)
#define statfs statfs64
#endif

[jmroot (Joshua Root)]

It built on 10.6 i386. I can't test anything on ppc but feel free to take it up with upstream.

Ok, just for the record, redefining as such does not yet work, since:

./Modules/posixmodule.c: In function 'os_fstatvfs_impl':

Thanks for testing i386, I cannot check that now.

Replying to jmroot:

It built on 10.6 i386. I can't test anything on ppc but feel free to take it up with upstream.

Okay, this fixed it:

#if defined(__i386__) || defined(__ppc__)
#define statfs statfs64
#define fstatfs fstatfs64
#endif

Warnings, as expected, are there, but no more errors (and no extra flags, just the patch above):

Now, the question is: is this correct solution?

This is the relevant header in the OS: ​https://github.com/barracuda156/10.6-PowerPC-SDKs/blob/main/MacOSX10.6.sdk/usr/include/sys/mount.h

16. S. I am not gonna try submitting a PR for any of the pythons, but having a better fix for myself will be nice.
