optimizer bug for AIX 4.3.2

Greetings,
I was building ddd ver 3.1.5 on a box running AIX 4.3.2 using egcs 1.1.2, when I got a compile error on source file DispBox.C.  The error message displayed was:
/tmp/ccnrsHXD.s: line 10676: 1252-151 This instruction form is not valid for PowerPC.
        The register used in operand two must not be zero and
        must not be the same as the register used in operand one.

I was able to get a clean build by removing the "-O2" from the CXXOPT and CFLAGS macro in the ddd/Makefile.

Sincerely,
Richard Leffingwell
