Oh  I'll adjust my level of excitement accordingly ;-)

Thanks for the quick response !

Unfortunately none of the math code is even implemented.

The only part that somewhat works is the decimal float printf code,
which is buried under --enable-experimental in mingw-w64-crt. It isn't
exactly widely tested either.

Here is the 'real' fix for it. Please review.

(I really hate this C-ish code but this way it looks like how 
`__udivdi3` was implemented.)

 7.

GCC targeting i686 _may_ generate an external call to the function in
question when divding a 64-bit (DIMode) integer with another one.
Since we are linking against a fake libgcc, this function is not available.

[Mingw-w64-public] How to access _Decimal64 functions in math.h

[sisyphus1]

Hi,

math.h prototypes a number of _Decimal32, _Decimal64 and_Decimal128 
functions - eg:

_Decimal64 __cdecl expd64(_Decimal64 _X);

But when I try to compile (gcc -o d64.exe d64.c):

/***/
/* d64.c */
#include 

int main(void) {

_Decimal64 x = 2.3DD, ret;

ret = expd64(x);

return 0;
}

/***/

All I get is:

C:\Users\sisyphus\AppData\Local\Temp\cc2vb9go.o:d64.c:(.text+0x2e): 
undefined reference to `expd64'
collect2.exe: error: ld returned 1 exit status

What else is needed ?

Cheers,
Rob
