OK, it works that way.
I have been able to recompile with the new gcc a program which uses the 
OpenMP library libgomp, and thus indirectly libpthread.
The only glitch remaining is a missing libgomp.spec file.
I brought one fron an equivalent linux system to succeed.
Apparently libgomp.a and libgomp.dll.a are contained in
gcc-core-5.3.0-2-mingw32-bin.tar.xz
but libgomp.spec is missing.

Thanks anyway
