/* Using flint headers together in the same module as headers from
 * some other libraries (pari, possibly others) as it defines the
 * macros ulong and slong all over the place.
 *
 * What's worse is they are defined to types from GMP (mp_limb_t and
 * mp_limb_signed_t respectively) which themselves can have system-dependent
 * typedefs, so there is no guarantee that all these 'ulong' definitions from
 * different libraries' headers will be compatible.
 *
 * When including flint headers in Sage it should be done through this wrapper
 * to prevent confusion.  We rename flint's ulong and slong to fulong and
 * fslong.  This is consistent with flint's other f-prefixed typedefs.
