The problem with those files is that the source file contains lines like this:

#line 1042 "y.tab.c"

but that source file does not exist, as it is renamed to gram.c.

We could fix that in one of two ways:

1) Use bison's -o option to put the output file in the right place directly, 
if we are dealing with bison (and don't bother to support code coverage 
analysis with other yaccs), or

2) Run a pattern replacement across the grammar output files as their are 
renamed.

Comments?
