When IPHREEQC_NO_FORTRAN_MODULE is defined, the type of the last parameter of SetBasicFortranCallback() function is size_t, which is defined in stddef.h.
Without this fix, IPhreeqc.h is not self sufficient when IPHREEQC_NO_FORTRAN_MODULE is defined, leading to compilation error when it's included in a project.
