-# XXX this module has *lots* of code ripped-off quite transparently from
-# build_ext.py -- not surprisingly really, as the work required to build
-# 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.
