Hi Grischka,
Using your advice, I added #if !defined(TCC_TARGET_ARM) around all code
directly or indirectly using ldouble_long which solved warning.
If you agree, I'll push this change on mod but IMHO it should be done the
other way, #if defined(<targets-that-need-it>)

Nope. Just #ifdef out the entire function.
