FWIW, using mingw.org's gcc-4.5.2 release, the test passes:

$ g++ -fopenmp omp_test.c -o omp_test -lpthread
$ ./omp_test.exe
OMP : All looks good

Relevant installation data:
gcc-core-4.5.2-1-mingw32-bin
gcc-c++-4.5.2-1-mingw32-bin
libgcc-4.5.2-1-mingw32-dll-1
libstdc++-4.5.2-1-mingw32-dll-6
libgomp-4.5.2-1-mingw32-dll-1
mingwrt-3.18-mingw32-dll
mingwrt-3.18-mingw32-dev
w32api-3.17-2-mingw32-dev
pthreads-w32-2.8.0-3-mingw32-dev
libpthread-2.8.0-3-mingw32-dll-2

I believe this is because TLS support was added to the mingw(32) runtime in
late Jan 2010, thanks to Kai's work:

(Although a full compiler suite, and mingw runtime, with TLS support was not
officially released until March 2010)
