Compared values are not the same (powtest.cpp:149)

Hmm, well our implementation interpretes the ISO C99 definition
"pow (x, y) signals the invalid operation exception for finite x < 0
and finite non-integer y. Therefore has as result -Nan.
Having here result +Inf looks wrong to me.
Cheers,

Attached is an updated test program.
It will now show all failures at once instead of terminating after the
first test failure.

Visual C++ 2010 and GCC on Linux give the same expected output for these
tests and pass. I just think it would be good if MinGW-w64 gave results
that were more consistent with Visual C++ 2010 and GCC on Linux. The
tests are based on what Google V8 expects to be the correct output - the

Hi,
I am getting some inconsistencies for the C pow() function between
MinGW-w64 and Visual C++:
compare(INFINITY, pow(-INFINITY, 3.1));
Compared values are not the same (test.cpp:145)
Expected (INFINITY): 1.#INF00
Actual (pow(-INFINITY, 3.1)): -1.#IND00
compare(+INFINITY, 1.0/pow(-INFI
