No, I doubt that. The symbol it is having problems linking with is
defined in $GEMS/common/util
The issue here is that Ruby/Opal Makefiles will build the object files.
Then to build a Simics module, we use the Virtutech Makefile which may be
using a different compiler. The compilers do not seem to agree on the
names of mangled symbols.
This problem comes up frequently on the list. We currently do not have a
clear, bullet-proof solution.
