I appreciate everyones help. I finally found the problem - though I still do not mostly understand it. The header files for the classes with the problems contained #pragma interface "xxx.h" but the source files for those classes did not contain #pragma implementation "xxx.h" Either eliminating the #pragma interface instances or adding the #pragma imlementation corrected the problem. I have not been able to find any reason one would need either pragma with current versions of gcc. Thank you.
