Well, this bug is configure/environment related and not a bug of gcc AFAICS.
So I close this as invalid.

Should I conclude that the MinGW site is now www.equation.com?

Its a shame that www.equation.com doesn't tell us how to obtain their source
code for the gcc, gdb ands make binaries.

No one has had put them there.

I did not build MinGW 4.3.0. I got it from the official MinGW site
(gcc-4.3.0-20080502-mingw32-alpha). I have also found that on www.equation.com
there are even newer versions (binaries), like 4.3.3 with OpenMP 2.5, 4.4.0
with OpenMP 3.0 and MinGW 4.5 compilation snapshot. They seem to work fine with
OpenMP. They aren't present on the official MinGW site. Why?

Let us forget everything about libpthread. MinGW fails to link the sample
programme at the command
gcc -fopemnp test.c -gomp -o test.exe

My question is how should I link this programme.

Your libpthreads is doing something wrong.

libpthread is needed to link libgomp, otherwise you get unresolved references
like
c:/mingw/bin/../lib/gcc/mingw32/4.3.0/libgomp.a(parallel.o):(.text+0xe):
undefin
ed reference to `_imp__pthread_getspecific'. 
Symbol pthread_getspecific is in libpthread.
