OK, things are getting clearer after studying a bunch of Makefiles and seeing what I have to do to make things happen.

Here's what I know:
1. To build a relocatable library for libCom, I have to pass options "-shared -fPIC" through to g++ when I'm creating the relocatable library.  This works fine, and I can create and use the library sort of successfully.  I'm still looking for the exact variable to set to pass these values.  have tried setting about every variable in my new "CONFIG.Common.netbsd-x86" file, and currently have it set in COMPILER_LDFLAGS.  However, when I run gmake with these options selected in  COMPILER_LDFLAGS, it will create a properly library, but fails to create a proper executable.

2. To build an executable, I have to be sure NOT to pass the "-shared" option through to g++.  I demonstrated that this works by deleting the incorrectly build 'antelope' program that is linked after the library is built, delete the "-shared" flag from my new "CONFIG.Common.netbsd-x86" file and rerun gmake.  This will recreate the antelope program, which appears to be functional.

I've moved down to another problem in the 'ca' directory now, probably caused by something I just haven't defined yet, but would like to figure out how to pass the "-shared" flag to the relocatable library creation function, correctly.  I don't see anything in Chapter 4 of the Developers Guide about how to do it, so I'll see if anyone has any idea.

Looks like most of the Make files were done by jba (I'm taking that to be Janet Anderson, I hope... She still doing work on this, or anyone have a suggestion?
