Hi,
This is a regression caused by rev 3993. Could a gatekeeper review this
patch? Thank you very much.
For a small case below, it will got link failure:
> cat 1.c
extern void foo(int a);
int main()
{
foo(5);
}
>cat 2.c
void foo(int a)
{
printf("a = %d\n", a);
}
>opencc -ipa 1.c 2.c

lookup error:

In osprey/common/com/dwarf_DST_producer.cxx: the function DST_get_dirname
is declared as “static char*”, However, I find in
osprey/be/com/clone_DST_utils.cxx, there is an “extern char*
DST_get_dirname”, a static function can’t be “extern”, and removing the
"static" is able to solve this problem.
