Hi, The removal of the scm_i_* functions is an ABI break in the stable 1.8 series. It should be reverted. (It's a great fix for master though.)
It breaks apps compiled with older versions of guile 1.8. Guile-gnome is not affected too much -- a couple instance of scm_i_symbol_length (not something that can currently be dealt with with version #ifdeffing, as the version is still 1.8.5), but more seriously the port table, with the scm_i_port_table_mutex. (The port API sucks, I know.) Thanks, Andy -- http://wingolog.org/
