botan @2.19.2: fails at patching stage

[MaintenanceCosts]

botan fails to install, at the patching stage, during a migration from Monterey to Ventura. It worked fine when I installed it on the Monterey system some time ago. I've tried cleaning and reinstalling botan, and then uninstalling and reinstalling all of MacPorts. No change. main.log is attached.

main.log with error

The log shows the problem is:

patching file 'src/build-data/cc/clang.txt'
1 out of 1 hunks failed--saving rejects to 'src/build-data/cc/clang.txt.rej'

The patch applies fine on my Catalina system, with fuzz:

patching file src/build-data/cc/clang.txt
Hunk #1 succeeded at 76 with fuzz 2 (offset 3 lines).
patching file src/build-data/cc/gcc.txt
Hunk #1 succeeded at 89 with fuzz 1 (offset 2 lines).

Several other tickets are revealing to us that the patch utility on Ventura does not support applying patches with fuzz. The patch should be regenerated. Somebody should also report this problem to Apple.

I suspect it's WAI, and that's not really a bad thing. Patches with fuzz can "succeed" in applying but produce an incorrect file.

What's WAI?
