140!-- WARNING: For compatibility of derived types, the BIND attribute is required, and interoperable C
141!-- datatypes must be used. These type are hard wired here! So changes in working precision (wp, iwp)
142!-- will not affect the particle_type!
143!-- The main reason for introducing the interoperable datatypes was to avoid compiler warnings of
144!-- the gfortran compiler.
145!-- The BIND attribite is required because of C_F_POINTER usage in the pmc particle interface.
