Jim,
FYI, I'm seeing:
gdb/macrotab.c:504: warning: `best_depth' might be used uninitialized in
this function
gmake: *** [macrotab.o] Error 1
for the code:
/* It's not us. Try all our children, and return the lowest. */
{
struct macro_source_file *child;
struct macro_source_file *best = 0;
int best_depth;
for (child = source->includes; child; child = child->next_included)
{
struct macro_source_file *result
= macro_lookup_inclusion (child, name);
if (result)
{
int result_depth = inclusion_depth (result);
if (! best || result_depth < best_depth) <-- HERE
{
best = result;
best_depth = result_depth;
}
}
}
return best;
}
enjoy,
Andrew
