Seems I was wrong. Uhm. It's late here... Anyway, I've really
running it now.
If we add this patch, we should also add the bits in libm:
#ifndef HAVE_SQRTL
long double
sqrtl(long double x)
{
return sqrt((double) x);
}
#endif
#ifndef HAVE_COSL
long double
cosl(long double x)
{
return cos((double) x);
}
#endif
#ifndef HAVE_SINL
long double
sinl(long double x)
{
return sin((double) x);
}
#endif
or we just compile stubs.c in and the gcc provided bits.
But I guess we would also not to link against libm then.
