commit d10c572e38a888e4f999c7f3229781e53b9a74ec
Author: Ludovic Courtès <address@hidden>

    Remove potential "uninitialized variable" GCC warnings.
    
    * libguile/vm-i-scheme.c (vector_ref, vector_set, BV_FIXABLE_INT_REF,
      BV_INT_REF, BV_FLOAT_REF, BV_FIXABLE_INT_SET, BV_INT_SET,
      BV_FLOAT_SET): Explicitly initialize all locals, to make some versions
      of GCC happier.  Patch by Dale P. Smith <address@hidden>.
