    Fix compilation when SCM_I_PTHREAD_ONCE_INIT is not aggregate
    
    * libguile/scmsigs.c (scm_i_signals_post_fork): It's possible for
    SCM_I_PTHREAD_ONCE_INIT to be a braced initializer.  In that case when
    this initializer is re-used as an assignment, it needs the type to
    instead be treated as a C11 literal.  Fixes compilation on Mac OS.
    
    Thanks to Tony Garnock-Jones for the patch.
