MZ_VERSION_BUILD became an octal number in 3.0.0, that becomes invalid with certain version numbers

I was using OCIO with minizip-ng 3.0.9, and it broke the compilation with this error message:

/path/to/OpenColorIO/src/OpenColorIO/OCIOZArchive.cpp:530:5: error: invalid digit '9' in octal constant
#if MZ_VERSION_BUILD >= 040000
    ^
/path/to/minizip-ng/include/mz.h:18:47: note: expanded from macro 'MZ_VERSION_BUILD'
#define MZ_VERSION_BUILD                (030009)

Looking at the history of the project, since the version bump to 3.0.0, the problem exists:

6f17da5

As you can see, the diff shows that the version number went from 21006 (decimal) to 030000 (octal) which is a net reduction of the version number in the first place because 030000 octal is 12288 in decimal.

Later, we see the use of 'a' for the digit 10, which suggests that the true number you want to generate is a hexadecimal number. Would you mind fixing your processes?

Thanks. I have added 0x prefix to it.

Thanks, that was really, really quick 👍🏻

It seems like it could also have been changed to 30010 and 40004. If sticking with hex, it seems like a new release of 3.X with the hex version might be in order.
