I assume so, yes. At least that is same behavior as happening with
*nix toolchain.
But well, I can't find here specific description for x87 case and -1 on 32-bit.

Kai, is it right when i run problem code with -m32 switch and it go to
defines with long double?

No problem, nevertheless I think I will simply replace the == 2 case
by an '#else'. The == 1 case shouldn't be reachable for x86/x64,
anyway I think we should keep it for completness.
Thanks,

Applied change at rev 5518 on trunk.

That code is wrong for 64-bit, as here float_t is float derived, and
double_t is double derived in all cases.

First, I am able to resolve C's preprocessor myself, secondly don't
cite me wrong. I wrote that this code we have in math.h could be
replaced by:
#if defined (__x86_64__) || (defined (__FLT_EVAL_METHOD__) &&
__FLT_EVAL_METHOD__ == 0)
typedef float float_t;
typedef double double_t;
#else
typedef l
What do you think about next code?
#if defined(__FLT_EVAL_METHOD__)
# if ( __FLT_EVAL_METHOD__== 0)
typedef float float_t;
typedef double double_t;
# elif (__FLT_EVAL_METHOD__ == 1)
typedef double float_t;
typedef double double_t;
# elif (__FLT_EVAL_METHOD__ == 2)
typedef long double float_t;

It not working because
#if defined (__x86_64__) || (defined (__FLT_EVAL_METHOD__) &&
__FLT_EVAL_METHOD__ == 0)
is
# if 0 || ( 1 && 0)

You meant that this code
#if defined (__x86_64__) || defined(__FLT_EVAL_METHOD__)
# if defined (__x86_64__) || ( __FLT_EVAL_METHOD__== 0)
typedef float float_t;
typedef double double_t;
# elif (__FLT_EVAL_METHOD__ == 1)
typedef double float_t;
typedef double double_t;
# elif (__FLT_EVAL_METHOD__ ==
You missed my point. I meant by replacing here the hole
__FLT_EVAL_METHOD__ block by the code I've shown earlier ... we actual
don't need to check different method-types as they can't occure

Huh? It should work, as there is a defined #else case. Have you

Hmm, well, I see. We could simplify code here.

Hmm, I don't see the point why we should limit that for x64 case to
__FLT_EVAL_METHOD == -1? In all cases it has simply to use
float/double for x64. Btw AFAIK is *nix using same approach.
What is actual the issue you still get?
