I don't quite understand the issue. Ok I see access of the structure in
core.c but how is that an issue? Aren't the headers that define
scm_t_port correct? (in systems where is 120-byte to actually define an
120-byte structure and otherwise?). Why would the size of off_t cause
issues if the header is the same in guile and gnutls? Is it a guile
issue or gnutls' guile code?
