Description

Definitions of support template function occur after their use. The following test case fails:

$ cat test.cpp; gcc -c test.cpp
template < class charT >
void f ()
{
    g (charT ('a'));
}

template < class charT >
void g (charT)
{
}

int h ()
{
    return f< char > (), 0;
}
test.cpp: In instantiation of 'void f() \[with charT = char\]':
test.cpp:14:23:   required from here
test.cpp:4:5: error: 'g' was not declared in this scope, and no declarations were found by argument-dependent lookup at the point of instantiation \[-fpermissive\]
test.cpp:8:6: note: 'template<class charT> void g(charT)' declared here, later in the translation unit

The culprits are test_hash, test_weight_val, etc. Comeau and gcc fail, icc and SUNPro CC pass.
