Does this example covers what you have in mind ? I am not so familiar
with this feature of setuptools:

Name: hello
Version: 1.0

Library:
    BuildRequires: paver, sphinx, numpy
    if os(windows)
        BuildRequires: pywin32
    Packages:
        hello
    Extension: hello._bar
        sources:
            src/hellomodule.c
    if os(linux)
        Extension: hello._linux_backend
            sources:
                src/linbackend.c

Note that instead of os(os_name), you can use flag(flag_name), where
flag are boolean variables which can be user defined:
