Struct BuildFlags

pub struct BuildFlags(pub HashSet<BuildFlag>);

A list of python interpreter compile-time preprocessor defines.

PyO3 will pick these up and pass to rustc via --cfg=py_sys_config={varname}; this allows using them conditional cfg attributes in the .rs files, so

#[cfg(py_sys_config="{varname}")]

is the equivalent of #ifdef {varname} in C.

see Misc/SpecialBuilds.txt in the python source for what these mean.
