Nik,
actually I've just modified it to the following that still tries to
detect pread(). Can you test and report?

Hi GDAL devs
It appears as though ‘pread64’, introduced in 3.6.0, has broken
building on iOS in the same way that other ‘…64’ errors used to occur
on version 3.5.0 before being patched for 3.5.2.
The attached patch (text content also pasted below) allows the build
to continue past that point for iOS (and Mac Catalyst). I’m just an
ignorant hobbyist who doesn’t really understand a lot of this stuff,
so please check that what I’ve done here is correct! :-) If it’s
all OK, then please apply this (or similar) patch for the next release.
Patch queued in https://github.com/OSGeo/gdal/pull/6673
Thanks
