  Hi, 

with master on my laptop the following tests fail when building the 32bit abi for x86-64:
FAIL: math/test-double-j0
FAIL: math/test-float-ctan
FAIL: math/test-float-j1
FAIL: math/test-float-y0
FAIL: math/test-float-y1
FAIL: math/test-float32-ctan
FAIL: math/test-float32-j1
FAIL: math/test-float32-y0
FAIL: math/test-float32-y1
FAIL: math/test-float32x-j0
FAIL: math/test-float64-j0

The normal 64bit abi passes fine.

Could you resend this with a proper commit message and Cc:
<fw@deneb.enyo.de>, please?  Then I can apply it with “git am” and push
it.  The patch itself looks fine.

Thanks,
