'-O' is the recommended optimization level. No problem there.
'-pipe' only affects the way files are passed between different phases
of the compilation process, so it makes no difference to the end
result. Not a problem.
'-g' adds some extra symbols to the object files, but apart from being
bigger they should otherwise be just about identical to binaries
compiled without '-g'. However, unless you override the setting of
the STRIP make variable all your work will be in vain, as the debug
symbols will be stripped out when you do the installworld. Unlikely
to cause problems, even with all the debug symbols.
Cheers,
Matthew
