- include/ruby/ruby.h: constify RRational::(num,den) and RComplex::(real,imag). Add macro to set these values:
- RCOMPLEX_SET_IMAG() This change is a part of RGENGC branch [ruby-trunk - Feature #8339]. TODO: API design. RRATIONAL_SET(rat,num,den) is enough? TODO: Setting constify variable with cast has same issue of r40691.
- complex.c, rational.c: use above macros.
