Unable to build: 'algorithm' file not found

[mwlon]

I ran

mkdir build; cd build; cmake ..
make btrblocks -j10

and got a few errors of this format, by way of fastpfor:

.../btrblocks/build/vendor/lemire/fastpfor/src/fastpfor_src/headers/common.h:34:10: fatal error: 'algorithm' file not found
   34 | #include <algorithm>
      |          ^~~~~~~~~~~

Some version info:

% clang --version
Apple clang version 16.0.0 (clang-1600.0.26.6)
Target: arm64-apple-darwin24.3.0

The <algorithm> header should exist since at least C++ 11, so it should work if your compiler setup is correct.
Judging from your other issues, you managed to get it to compile after all.

Is the fix something that should be contributed upstream, or was it a local issue?

I switched to Linux - I still haven't been able to build it on Mac.
