Doesn't work with Emscripten

[Maeiky]

I just try it out with Emscripten to use Cello on the Web. But unfortunately it doesn't work

Here is my log:

See my fork to get this result: https://github.com/Cwc-Lib/Cello

Well, by disabling GC (CELLO_NGC) and some tests, we can get an interesting result. Try it out here: Test Suite

However, we have to remove the following tests to avoid a crash:

• suite_array
• suite_file
• suite_float
• suite_list
• suite_mutex
• suite_thread
• suite_zip
• suite_exception

Nice! I don't know what the error before was but I guess perhaps Emscripten doesn't like the GC scanning the stack...
