But won't dlopen ("/lib/mmx/libc.so.6", ...) be handled by:
if (! IS_ABSOLUTE_PATH (in_pathname) || solib_absolute_prefix == NULL)
temp_pathname = in_pathname;
else
{
[Catting of prefix and pathname]
}
/* Now see if we can open it. */
found_file = open (temp_pathname, O_RDONLY, 0);
That counts as an absolute path case, right?
I can't see why we'd rely on the first openp to handle dlopen ("/lib/mmx/libc.so.6",
...) since it's an absolute path and should be handled by the code above. That's why
I suggest we know we should look in solib_search_path (and thus should get rid of the
leading '/' which makes it an absolute path).

No problem; my bad. I didn't know solib-search-path could be colon separated, though
I see that now in openp.
