# a static library from a collection of C source files is not really all

# that different from what's required to build a shared object file from
|

# a collection of C source files. Nevertheless, I haven't done the

|
# necessary refactoring to account for the overlap in code between the
|
|
# two modules, mainly because a number of subtle details changed in the
|
|
# cut 'n paste. Sigh.
