Found where it's manifesting, now to figure out why ... from the
guile-1.8.3 directory, if I do:
cpp -I. -DHAVE_CONFIG_H libguile/numbers.c -o foo.cpp
I find that this line in numbers.c
6081: return scm_from_complex_double (cexp (SCM_COMPLEX_VALUE (z)));
expands to this:
return scm_from_complex_double (cexp (((((scm_t_complex *)
((((scm_t_bits) (0? (*(SCM*)0=((((SCM *)((scm_t_cell *) (((scm_t_bits)
(0? (*(SCM*)0=((((z))))): (((z)))))))) [((1))]))): (((SCM *)((scm_t_cell
*) (((scm_t_bits) (0? (*(SCM*)0=((((z))))): (((z))))))))
[((1))]))))))->real) + __I * (((scm_t_complex *) ((((scm_t_bits) (0?
(*(SCM*)0=((((SCM *)((scm_t_cell *) (((scm_t_bits) (0?
(*(SCM*)0=((((z))))): (((z)))))))) [((1))]))): (((SCM *)((scm_t_cell *)
(((scm_t_bits) (0? (*(SCM*)0=((((z))))): (((z))))))))
[((1))]))))))->imag))));
So hunting back to where SCM_COMPLEX_VALUE is defined in numbers.c, we
get
168 #define SCM_COMPLEX_VALUE(z) \
169 (SCM_COMPLEX_REAL (z) + _Complex_I * SCM_COMPLEX_IMAG (z))
So it looks like _Complex_I is rendering as __I - and that prpbably
isn't correct.
