* blockframe.c (block_innermost_frame): Uncomment.
Return NULL if passed NULL.
* frame.h: Declare it.
* expression.h (union exp_element): Add field block.
* parse.c (write_exp_elt_block): New function.
* expression.h (OP_VAR_VALUE): Now takes additional struct block *.
* *-exp.y: Write block for OP_VAR_VALUE.
