Knobs for users are at least better than configure-time knobs (and params
are to a large extent knobs for GCC developers rather than for normal
users). For almost any piece of free software - not just GCC, or even
mainly GCC - it's a pain for those using the software on multiple
GNU/Linux distributions, or on GNU/Linux and on other systems, when the
same software gratuitously behaves differently on different systems
because the respective distributors / builders decided to configure it
differently. For the multi-platform user it's better not to have all the
configure-time knobs, so they only need to set up their personal
configuration to override cases where their taste differs from one fixed
default, and not override every case where one distributor has decided to
change the default.
