Well, no, If I look at 1.8.7 I see the following in tags.h:
typedef struct scm_unused_struct * SCM;
or
typedef scm_t_bits SCM;
The struct is clearly named in this case. I did not look at 1.9.4.
I provided a very short sample program that elicits the bug ..
you can play with it. Running gcc -E on it quickly revealed
what was happening.
