I'm using MinGW and GSL for years.

You shuold get all tests passed wiht the  -O2 omitted. Usually the
optimization flag can introduce some errors (for example the old
"montecarlo" issue). Now all the issue I observed in the past are fixed,
using the GCC 4.5.0 (I haven't tested the latest 4.5.2 so far)

Today using MinGW (full MinGW not Cygwin) is possible to pass all the
tests.  Moreover using -ffloat-store was fixing all the bugs related to
extra precision of X86, in the past.

So my advice is : try the MinGW compiler 4.5.2 using the latest package
for binutils, winapi and runtime libs.

Hope this helps
