Compiling the test-program below results in an undefined reference to __tructfxf2:

$ gcc -v
Reading specs from /opt/gcc-pre3.4/lib/gcc/ia64-hp-linux/3.4/specs
Configured with:  : (reconfigured)  : (reconfigured)  : (reconfigured) 
Thread model: posix
gcc version 3.4 20031119 (experimental)
$ cat t.c
long double f (int g)
{
        union {
                int g;
                long double d;
        } u;
        u.g = g;
        return u.d;
}

int main (int argc, char **argv)
{
        return f(argc);
}
$ gcc -O /tmp/t.c
/tmp/cc6b8Pzg.o(.text+0x32): In function `f':
: undefined reference to `__trunctfxf2'
collect2: ld returned 1 exit status

It doesn't matter whether -O or -O2 is specified.  Dropping -O makes the problem
disppear, however.

I discovered this problem while trying to compile libc with gcc-pre3.4.
