After much svn bisecting, I find I cannot build any revision of fpc
trunk after r43472 (Sat, 16 Nov 2019) on macOS 10.14.6 due to the
error:

Code: [Select]fgl.pp(973,11) Error: Identifier not found
"IsManagedType"
fgl.pp(2092) Fatal: There were 1 errors compiling module, stopping
Fatal: Compilation aborted

Any ideas?

Are you starting the build with FPC 3.0.4? The latest release is
always the only supported starting compiler for trunk.

I'm building with 3.3.1 (22 Oct 2019). Do I really need to reinstall
3.0.4? I've not done in the past.

Yes, you do. As Jonas said, building trunk is only supported with the
last release which is 3.0.4. Anything else might break at any time and
we don't care to keep it from breaking.

QuoteAnything else might break at any time and we don't care to keep
it from breaking.
And the reason for that is that it is unfeasible to make it possible
to build trunk with every single revision of FPC ever released,
because every one of those might be missing a feature or have a bug
that breaks it. Adding workarounds for a single FPC version for
bootstrapping is one thing, but doing that for everything is
impossible (and it would be a huge time sink).

Got it, thanks!
