Platform : Windows XP Sp3 , latest (29th Jun 2009) msys,binutils,make,runtime and GCC
4.4.0

using optimization (CFLAGS = -O2 -fexceptions) the testing fails at
(first error)

make[2]: Leaving directory `/home/Massimo/gsl-1.12/integration'
make check-TESTS
make[2]: Entering directory `/home/Massimo/gsl-1.12/integration'
FAIL: qawc(f459) elist (1.8329242496630777e-015 observed vs
1.8330829482071535e-015 expected) [744]
FAIL: test.exe

using -ffloat-store fix the issue.

Brian Gough (GSL maintainer) is confirming the issue (fails the same test) using Gcc 4.4.0 under Linux.
Brian also confirmed that no fails were present using gcc 4.3.0 under Linux.

    Not a MinGW bug.

    Although your problem may be interesting and causing you problems you wish answers to, it is not a problem with the MinGW runtime,
    w32api, GCC, binutils or msys. Your BUG report has therefore been deleted. If you feel that this needs further discussion then
    please post to mingw-users@lists.sourceforge.net.

    Thanks for your interest in the MinGW Project,
    MinGW Project Administrators
