@ifitchet I was able to build python 3.15.0b3 on linux-64 locally:

This looks wrong, btw. Our patch shouldn't be introducing new things -- although I got the same thing when I tried to regenerate the patches.

Maybe it works because "Hunk already applied" or something we'd need to look closely at the build output.

The first bit rem ... seems OK as that is in the original 0002-*.patch. But that is the only change in the original patch!

The second bit looks like git done goofed:

So the if /I ... bits were in the original bump from 3.14.6 to 3.15.0b3. So they should not also be in our patch.

My suspicion is that git sees the if /I lines as having changed with the 3 lines of context and has included them.

However, it looks as though it has also deleted the if "%do_pga%" ... lines. Which would be bad... Did it echo "Cannot cross-compile with PGO" ??

Given that it built... 🤷

Thanks for catching that.

0002 and 0004 still each have a single intentional change vs our master branch; the Clean/CleanAll and stdlib_zip lines are just upstream context from the 3.14→3.15 move.

0014 and 0022 were the real regressions — fixed in 633a0fe.

Ah, the issue with 0022 is that it clashes with the line changed in 0008...
