I'd generalize from that.  Some of the many use cases for tcc are in
the bootstrapping category:  start from an old/substandard C compiler
(e.g., old msvc, or mescc) to get a more modern/standard C compiler.
The next step is sometimes using tcc to compile gcc-2.95.0 or gcc-4.7.4,
which gets you a usable C++ compiler.  Lots gets written on this topic.
Here's one link, that prominently mentions TinyCC:
