What is the difference between those 3?
OPT= always to my best knowledge
NEWOPT is opt only for later cycles and the rest, iow not for the first FPC bootstrap cycle (that might be started with an older compiler version). So it is for additional options that are not supported by the bootstrap compiler, but are supported by the newer compiler.
I don't know an "OPTFPC", and no files grep for it in the FPC or lazarus repos ?

I came across OPTNEW here
https://wiki.freepascal.org/LLVM
But now I am trying to play with the rather old fpc build script for
the laz installer.
And it calls
%MAKEEXE% compiler_cycle PP=%RELEASE_PPC% >> %LOGFILE% 2>&1
%MAKEEXE% rtl_clean PP=%COMPILER% >> %LOGFILE%
%MAKEEXE% rtl packages PP=%COMPILER% OPT="-Ur -CX" >> %LOGFILE%
%MAKEEXE% utils PP=%COMPILER% OPT="-CX -XX -Xs"
DATA2INC=%SOURCE_DIR%\utils\data2inc >>
...
And giving it just OPT=.... does not seem to do the trick.
Oh, yes of course, ideally rewrite that old script... Well "someday" ....
.... but I always use the toplevel makefile. I haven't tried to manually compile parts of the project for non debug purposes like that since FPC 1.0.x days...... Even the already old buildfaq doesn't document such partial compiling.
