Is this expected to not compile with -fno-implicit-templates?
---%<---
$ cat test.cc
#include <string>
std::string test(int i)
{
std::string t;
std::string s = "(";
t = "";
for (int r = i; r; r>>=1) {
if (r & 1)
t = "1" + t;
else
t = "0" + t;
}
s += t;
s += ")";
return s;
}
int
main(int argc, char *argv[])
{
std::string s = test(16);
return 0;
}
$ g++ -fno-implicit-templates test.cc
/tmp/ccai7t5T.o: In function `test(int)':

I am trying to fix a package, but it is documented to
require -fno-implicit-templates and instantiate templates
in one of the sources, but it instantiates templates for
its own types.
Thanks,
Paulo
