You know, I think I'd rather activate the stubs.c file than patch libm.
If libm is going to provide real "long double" functions, then it should
provide real ones, not faked lower precision ones.
stubs.c fills in the blanks for the parts that libm doesn't provide,
according to config.h. We can even add ifdefs to the config.h file if we
have some arches that provide the long double versions and others that do
not.
To be sure we're all on the same page, simply uncommenting stubs.c solves
your problem with no libm changes, right?
Cheers,
-Peter

Re: Solved: libstdc++ problem with recent CURRENT
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.
