libpano13-2.9.21 fails to build from source on macOS

[Caleb Xu]

Hello, I am trying to build libpano13-2.9.21 on macOS Monterey (12.1) on x86_64 architecture. I am seeing errors like this during the build step:

/tmp/libpano-20211230-23553-1kbwuty/libpano13-2.9.21/panorama.h:56:10: fatal error: 'endian.h' file not found
#include <endian.h>
         ^~~~~~~~~~

Looks like on macOS, endian.h lives at <machine/endian.h>, hence the error. I replaced the occurrence listed above with #include <machine/endian.h> and got it to build in my environment.

Note that macOS' <machine/endian.h> is not identical to Linux <endian.h> in terms of symbols/functions available. But seeing as the build completed, looks like whatever differences there may be might not an issue here. I can provide the header if needed.

Sorry, but for testing such things we released several release candidates. Why waiting to the to final release?

We are using only the preprocessor defines __BYTE_ORDER and __BIG_ENDIAN from endian.h. Are they on MacOS also defined?
