| Hmm. Works okay with cc -migrate -g on my 3.2 system. What is different? Can
you post an stdump of the .o file?

| Ah. A difference between C and C++. I actually believe C++ is correct
here (I keyed my bug while using C++). Is C++ correct?
C generates information for "numbers" with a simple Block/End. C++
also includes a Tag. So it must be that Tag that's providing the extra
output.
This is also the case with classes, and other things with tags....
greping stdumps for numbers:
(C)
2. ( 2)( 0) numbers Block Info symref 7
6. ( 2)( 0) numbers End Info symref 2
(C++)
2. ( 2)( 0) numbers Tag Info [19] enum(extended file 0, index 3)
3. ( 2)( 0) numbers Block Info symref 8
7. ( 2)( 0) numbers End Info symref 3

| Well you didn't say which compiler, and you personal name says "DEC C". I
initially typed "cxx ..." to compile it but did a double take.
Your explanation of the C++ behavior is correct. Which is right (c or c++) I
still am not sure.

I've been working on C++ for the past couple of weeks. I pulled the
typical engineer's mistake of talking as if everything pertained
directly to my project. :)
I'll remember to include compiler directions in my examples from now
on.
