Not clear if you wrote "single shared library" on purpose instead of "single 
static library". But for me the objective of COMBINE_LIBS usage would be 
getting a "single static library" for my app, which just works, and eliminates 
need of start-group, end-group, weird library ordering issues, etc. I'm not 
interested personally in a "shared library" because it'd run slower.

Personally my preference would be to do both the single libs and multiple libs 
in static format by default. Disk space is cheap, let's maximize user freedom 
and flexibility. But shared lib, since it performs less well, should be 
discouraged by default, although allowed if needed... some people prefer it 
because it's easier to patch security vulns if you can replace a buggy library 
for all the code on a system.

Matthew.
