Iain,

Apologies. I forgot about this. Seeing as I'm now using GNU 10.2.0 on my
Macbook...I guess it's working.

I currently do:

../gcc-10.2.0/configure --prefix=$HOME/installed/Core/gcc-gfortran/10.2.0
--enable-languages=c,c++,fortran
--with-sysroot=/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk |& tee
configure.log

when I configure it which is much as you suggested.

My guess is I worked with my admins nuking and restoring XCode until we got it
right (or something, government laptops are fun, no sudo, lots of
restrictions...).

Thanks for your help, and I can't wait for 10.3 or 11.0 or whatever is next! N

Note: I'm still on an Intel Mac, so I won't need to bother "Iain Sandoe, master
of M1 GNU" about that for a while. :D
