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 ?

.... 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.
