f2py indeed seems to skip names that collide with C keywords. The reason
probably is that it's not guaranteed that the symbol name is mangled to
"union_" but it could also become "union". If the name matches a C
keyword, there's probably no (sane) way to call the function from the C
language, and since f2py goes through C, it's not able to call that.
Whether this is a real problem in practice or not is then a different
The full list of "bad" names is
'max', 'min', 'flen','fshape',
