b19178f8f4 Fix consistent typo: it is FE_ALL_EXCEPT instead of FE_EXCEPT_ALL (this 
went unnoticed as the undefined macro evaluated to 0 and the expression
was always used with ~)

5198dd7ae2 Seems we need both sqrtl and _sqrtl as a weak alias - something must be 
wrong namespapce wise here, but this should make it build for now.

77e93a9cb9 Drop in a fabs() after the fsqrt(). 
While it may seem pointless, it the rouding mode is set to round towards
minus infinity then acos(-1) calculates atan2(sqrt(1.0 - 1.0), -1) the subtract
generates -0.0 which sqrt() preserves.
atan2(-0, -1) is -pi, but acos(-1) is expected to be +pi.
This might 'fix' the test failures seen in some environments, but they
are not failing due to an obvously incorrent x87 rounding mode.
