The new test classes added by the patch are missing from test/classes/module.mk. Here is a patch to fix this:

I have rebased the patch to cset:999f8257313b (test_classes.m renamed to classes.tst) and run a full "make check". Everything still looks ok.

The attached patch fixes the bugs in inferiorto().

Several other functions related to class precedence are rewritten for clarity, and tests are added to test/classes/test_classes.m.

[Note: this was initially submitted as patch #7946]

I meant "doesn'T behave as expected" and "fails silentLy"... The worse part is, I actually proofread my post before sending... Is there any way I can correct my post after sending it ?

The attached tests exhibit two bugs in inferiorto().

First bug: calling inferiorto() when the opposite precendence is already set fails silenty (neither does it generate an error, as expected, nor does it actually change the precedence relationship).

Second bug: calling inferiorto() when no precedence is already set generates an undue error.

Both are actually related to the same error in the C++ code. A patch with bugfix & tests will follow shortly.
