=The -K flag (described in some version of TFM, cc(1)) controls such

=embarrassed that that wasn't the first place you looked?-), there are
=three possibilities.  -Kmau (probably the default) generates code for
=an MAU.  -Kfpe ("floating point emulation") compiles your program to
=run on a 32100- or 32200-based system (that is, anything but a
=3B2/300).  -Kc ("compatibility") produces .o and a.out files that will
=run on any 3B2 ever made.

=While your reading the release notes, you should notice that -Ksd (or
=is it -Ksp? anyway, the default) tells the optimizer to increase your
=program's speed, while -Ksz will improve (decrease) your software's
=size.

That's fine if you have cc.  My system has fpcc only.  Now aren't you
sorry you were snide?
