GSL 0.9 Fails in test with VC++ 6.0

[Jose Miguel Buenaposada Biencinto <jmbuena at dia dot fi dot upm dot es>]

Hi again Brian,

Here we are trying to build a functional library of GSL 0.9 with Visual
C++ 6.0.

When we build it in debug configuration there is no errors at all in the
test cases, but
when we build the release versions of the libraries and the test
programs we
get 28 failures (See below). It seems to be related with the
optimisation flags
("maximizate speed" choosen, /O2 flag) because if we build all, in the
release
configuration, but changing the optimization to "default" then we get 0
errors.

This is a issue to investigate in more depth, I think ;-).

Best regards.
José Miguel.
