Well, I guess you can't declare inline functions in .cc files, only in
.h files.  Is this correct?  It makes sense, otherwise how would 
incremental compiling work....

Anyway, I inadvertently did this, and had an undefined symbol problem.
The functions I declared as inline came up undefined during linking.

I took off the inline declaration, and it compiles now.  If that was the
problem, perhaps it would be a nice addition to add a compiler error
message saying no inlines.....

You CAN use inlines in .cc files, but only for statically used functions.

GCC acts perfectly.

If you define an inline function in .cc files, no symbol is ever generated
by the compiler (obviously, since no separate function exists).  Similarly,
when declared in a .h file, no symbol is created.  Remember, .h files are
nothing special, they are just textually included into the .cc files.  I'm
not sure the compiler proper ever even looks at actual .h files, since they
should be merged in by the pre-processor.
