+// with gcc (any version) on a system which uses a non-GNU toolchain.
+// The problem is that gcc uses a weak symbol for a particular
+// instantiation and that the system linker usually does not
+// understand those weak symbols (seen on HP-UX, tru64, AIX and
+// others). Thus we force an explicit instanciation of this particular
+// template (JMarc)
