PIE Issues - To make a stable binary for my app, I needed to turn off
the hardening for the powerpc64 processor. I cannot, at this stage
determine if FPC deliberately supports hardening on POWER, I need to do
some more experiments. I suspect (but do not know) that FPC hardening
may be limited to x86 and ARM.

I have not heard back from sponsor Philipp Huebner,  (and thats
unusual) so he may be unhappy about me disabling PIE Hardening on
powerpc64.  Honesly, I very much doubt anyone is going to use it there
!

Sid/Bookworm Lazarus - At the time of writing, there was an issue with
Lazarus that I think you have fixed already (thanks!) whereby the name
of the package disagreed with the name that Lazarus uses internally (as
shown in ide/version.inc). This confuses Lazarus when it rebuilds
itself. I did not raise a bug because by time I went back to track it
down, I found you had already fixed it.  

The problem only arises when using the Lazarus IDE, not when using
Lazarus's LCL to build an app. And this problem existed, a few weeks
ago, in Bullseye, I have not been back there to test ....

No, no ticket, as you have fixed it in sid/bookworm, I guess you have
it under control in bullseye, if you are unsure I can quickly build a
fresh Bullseye and test.

OK, will do so (but I don't like logging bugs without trying to fix
them myself). Its an assembler  problem, FPC seems to make
a basecontentprovider.s file that it calls the assembler on and that
fails. I don't understand the process.  Needs someone who understands
POWER assembly code I am afraid.  The message is -

lib/powerpc64-linux/basecontentprovider.s:1112: Error: can't resolve
`.text.n_basecontentprovider_$$_geturiprefix$ansistring$$ansistring'
{.text.n_basecontentprovider_$$_geturiprefix$ansistring$$ansistring
section} -
`.BASECONTENTPROVIDER_$$_GETURIPREFIX$ANSISTRING$$ANSISTRING' {*UND*
section}

It does not prevent me from building my app so should not be discussed
in this thread, sorry !
