Hi Guilhem,
the problem was name mangling. Microsoft mangles both function *and*
variable names in C++.
The result was unresolved symbol error during the link.
Wrapping a variable in C_MODE_START/C_MODE_END definitely helps in this
case.

If I remember correct, this was my first try, but then serg noticed that 2
UUID generators( "normal" uuids and "short" ones) are completely different
things and do not have to wait for each other.
