ABORT(); ---> assert(); More specifically: if (x == y) ABORT (); --> assert (x != y); if (x != y) ABORT (); --> assert (x == y); if (x > y) ABORT (); --> assert (x <= y); etc. if (!x) ABORT (); --> assert (x); if (x) ABORT (); --> assert (!x); DeMorgan's Law's applied and manually simplified: if (x && !y) ABORT (); --> assert (!x || y); if (!x || y >= z) ABORT (); --> assert (x && y < z); Checked to make sure that assert() of an expression with side effects ensures that the side effects get executed even when asserts are disabled, and add a comment about this being a requirement of any "disabled assert" expression. * depend: * make-src-depend: * make-src-depend (PrintDeps): Fix broken code in make-src-depend so it does what it was always supposed to do, which was separate out config.h and lisp.h and all the files they include into separate variables in the depend part of Makefile so that quick-build can turn off the lisp.h/config.h/text.h/etc. dependencies of the source files, to speed up recompilation.
