/* The usertab function needs to be in a separate object or clang/gcc
optimize the code in such a way that the user-defined usertab gets
sent the wrong input.
NOTE: If a dummy usertab is included in your code, you may be unable
to also provide a user-defined usertab. If you use dynamic linking
this is sometimes possible: when the simulation executable provides
a usertab object, it will be part of the table of loaded objects and
when later loading the shared object version of ModelicaStandardTables,
the dummy usertab will not be loaded by the dynamic linker; this is
what can confuse C-compilers and why this function is in a separate
file).
The interface of usertab is defined in ModelicaStandardTables.c
